I know that the code didn't conform to *your* threading model. My point is that your threading model is, in a certain sense, wrong. It isn't what people expect, at least not people who are familiar with the Posix threading model. The documentation is in fact very misleading, with phrases like "like for any other shared resource", when you don't need external synchronization for other shared resources, *unless* someone is actively modifying it. Now, I'm not saying that the Posix model is the only legitimate one. But it is the one I, and most people working on Unix platforms, are familiar with, and expect. And it is a standard on those platforms. You can choose to ignore it, and to ignore what SGI has done in this regard. But in that case, you have to be aware that you are trying to create an island, in which you are different from everyone else. |> and why we insist that library users |> must write correct locking sequences outside the context of the |> library. As you well know, there is nothing in POSIX which |> dictates that a library internalize the locking vs. implying |> that the user code must hold a mutex lock. Posix only defines its own functions (most of which are either thread-safe, or have a thread-safe variant), and it only defines a binding for C for them. Other than that, we are left with general, language neutral statements like the one I quoted. Obviously, a library not specified by Posix can do what ever it wants. In practice, however, user expectations are based on what Posix does, and that leaves two alteratives: -- Model your library on the actual Posix functions, with full internal locking -- I can call write on the same file descriptor from two different threads, for example, without problems. A lot of people (although none of the experts I know) seem to expect this. Rogue Wave tries to do it, for example. IMHO, however, it isn't reasonable for a library which lets references (in the general sense) escape to the user -- Posix itself makes an exception for functions which return pointers to internal data structures. (It doesn't use those words, but if you look at the list of functions which are not guaranteed thread-safe, it includes exactly those functions, and no others.) -- Base your model on the general, language neutral statements. This is what SGI does, for example. The general statement is that I need a lock if more than one thread is accessing the "memory", and any thread is modifying it. Since the abstraction model of C++ prevents me from actually seeing the memory, one is lead to exterpolate "memory" to "object". This seems a reasonable interpretation to me. At least some experts agree -- the authors of the the SGI threading model, for example. (I consider the people who were working at SGI when that model was defined to be among the best threading experts in the world. That's just my opinion, but every time I've had a discussion with them, I've come out knowing more than when I went in.) You can, obviously, take the position that you have defined the threading model you wish to use, that you know better than everyone else, and that your decisions cannot be questioned. And I can take the position that you're just wrong, you don't know anything about threading, that g++ is worthless in a multithreaded environment, and publicize that opinion in various newsgroups. Such attitudes won't help either of us, however. This bug report came about because of a discussion in a news group. Basically, I said to watch out for std::string with g++ if you are in a multithreaded environment. I don't remember my exact words, but I'm pretty sure that the gist would have been that the g++ implementation of std::string does not behave as one might expect. I said it in a newsgroup, rather than making a bug report, because I knew of the text in the FAQ (or something similar), and I was convinced that no one here would consider it an error. Gaby suggested otherwise; that if I could describe a case where the code could fail, although no th

All I really ask is that the problem be recognized. As I said, it only affects certain specific cases, and there are acceptable work arounds. If the doc says explicitly, we're doing something different here, I can live with that -- I would suppose that there were some good technical reasons (or possibly non-technical -- the world isn't 100% controlled by technology yet) for it. Responses along the lines of "it's only hypothetical", or "you're not playing the game according to our rules", are not helpful. They're not helpful because I know that already. The window of vulnerability is exceedingly small, which means that creating a test case which reliably fails is exceedingly difficult. From your comments in the newsgroup, I was fairly sure that you would accept my next best approach. From what I know of the extremely high technical competence of the other g++ developers, including the original author of std::string, I rather thought that they would, too. I'll admit that the "hypothetical" bit surprised me. The fact that I am not playing according to the official rules is another issue -- I know that, too, but I feel 1) that the official rules aren't really the best with regards to usability, and above all, 2) the way they are formulated is somewhat "ingenious". Point 1 is, of course, personal opinion, but the fact that some experts are also led astray by the formulation is IMHO worth considering as a problem in itself. |> This is not because you're threatening to woersen g++'s reputation |> or disregard it in production use -- if it were that, I would not |> worry ;-). That's because you know that the competition is Sun CC (which is no competition at all), and that I don't get to choose the compiler anyway:-). Seriously, however, I think you understand why I might feel obligated in certain contexts to mention the fact that g++ does have problems with regards to threading. Not problems like pre 3.0 had, of course, but the fact is that it doesn't always conform to the local conventions. Sometimes, for some very good reasons, but differences have to be doubly documented, because people don't expect them. |> This is because no matter what we might say in our FAQ, |> if the behaviour is odd enough or singular enough, it entails Fear, |> Uncertainty and Doubt. That is not what we want. I think that's the key. People should feel at ease with the tool. Globally, I like g++ -- it's become my preferred compiler for most things.

The problem occurred in a large finite element analysis code I developed.
The toplevel logic was written in C++, and this was linked to a venerable
public domain numerical analysis library in Fortran. My testcase consists
of the following two files. You only get a floating point exception
if IEEE floating point exceptions are enabled. I don't know if it is possible
to do this from a pure Fortran program, but it is certainly possible to
do from C, and I find it important to do this in numerical codes so that
I can see errors where they occur rather than just propagating NaN's through
the program.
File "toplevel.c":
#include
main()
{
feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
killer_();
}
File "killer.f":
subroutine killer
write(6,'(x,e10.4)') 1.0
end
gcc -c toplevel.c

[Bug c++/21386] New: Inconsistent diagnostics for taking address of rvalue
g++ reports an error where a program attempts to take the address of an rvalue
of built-in type, but merely warns where it takes the address of an rvalue of
user-defined type:
$ cat test.cc
int i() { return 0; }
class A {};
A a() { return A(); }
int main()
{
int * pi = &i();
A * pa = &a();
}
$ g++-3.4 test.cc
test.cc: In function `int main()':
test.cc:6: error: non-lvalue in unary `&'
test.cc:7: warning: taking address of temporary
The first error message is also odd; "non-lvalue" is C terminology that is
rarely used in relation to C++.
I would expect an attempt to take the address of an rvalue of any type to result
in an error; it's banned by the standard and I can't think of any useful
semantics for it if it is allowed.

[Bug c++/21387] New: Unaligned writes on MIPSEL systems after typecast
See code below. After type-casting, the compiler incorrectly assumes that
'a.unaligned_int' is aligned on a word boundary. On a MIPSEL system (here a
Cobalt RaQ 2) a 'sw' assembler instruction is generated to store the value in
memory, resulting in a 'Segmentation fault'. Changing the 'sw' instruction to
'swl', the problem is solved.

[Bug c/21392] New: Wrong code generated for array of enum with "mode" attribute
Test code:
typedef enum { false, true } bool __attribute__((mode (byte)));
bool foo[16];
bool test (int i)
{
return foo[i];
}
This works with v3.3.3. With V4.0.0, the generated code is wrong -- it
references the array element as a word (4 bytes) yet indexes it as bytes. In
this particular test case, the generated code does unaligned loads (why is not
clear); in an example in my application where the bool array is on the stack, it
generated a regular word load, killing the program due to an unaligned access.
Presumably related: when I ask gdb what it thinks sizeof(foo[0]) is, I get 4
rather than the expected 1.

This patch fixes the issue for me:

The following is probably the correct patch (which I can't readily
check as I don't have autogen installed):

The same issue might affect "the __FD_ZERO macro present in glibc
2.0.x." and other places, but I can't readily test them.
