[Bug libfortran/21593] FAIL: gfortran.dg/dev_null.f90
--- Additional Comments From fxcoudert at gcc dot gnu dot org 2005-06-18

The problem is in the different behavior of ftruncate on /dev/null:
$ cat a.c
#include
#include
#include
#include
int main (void)
{
int fd = open ("/dev/null", O_RDWR);
ftruncate (fd, 0);
printf ("%d\n", errno);
close (fd);
return 0;
}
On linux, this code outputs 22 (EINVAL), while on freebsd it outputs 0. I
suppose the reason of the failure is similar for other platforms.
I'm sure what to do, but I don't think I'll take too much time thinking about
it, since this a low-priority bug really.
While we wait for this to be solved, I think we should make sure the testcase
only runs on linux and solaris (for which this is known to work).

[Bug java/22113] New: Buffer overflow in the lexical analyser while reading FP literals
There is a buffer overflow error in GCJ while reading in large FP literals, as shown by Jacks testcase 3.10.2-round-6 (and others). On my machine, this manifests itself only when "parse.y" or "lex.c" is recompiled at -O0 after a full bootstrap, like so: cd $GCC_SRC_DIR/gcc/java touch parse.y cd $BUILD_DIR make BOOT_CFLAGS='-O0 -g3' bubblestrap Compile the attached testcase before and after this. In my case, it gives the expected "Floating point literal too large error" only in the former case. The array "literal_token" in do_java_lex() in lex.c is 256 characters long, but the subsequent code merrily overwrites long literals past this limit. A silly patch to overcome this particular error is: Index: lex.c === --- lex.c 2005-06-18 17:04:00.0 +0530 +++ lex.c 2005-06-18 17:06:14.0 +0530 @@ -965,7 +965,7 @@ do_java_lex (YYSTYPE *java_lval) int parts[TOTAL_PARTS]; HOST_WIDE_INT high, low; /* End borrowed section. */ - char literal_token [256]; + char literal_token [512]; int literal_index = 0, radix = 10, long_suffix = 0, overflow = 0, bytes; int found_hex_digits = 0, found_non_octal_digits = -1; int i; But of course this won't do.

According to null(4) man page, reading or writing to /dev/null
on FreeBSD always succeeds. According to the ftruncate man page,
upon successful completion, the value 0 is returned.
The redhat system that I checked, identifies /dev/null as "a
special file" in null(4). The ftruncate man page specifically
states the behavior for "regular files". So redhat has wiggle
room with its use of errno.
POSIX
http://www.opengroup.org/onlinepubs/009695399/toc.htm
If fildes refers to any other file type, except a shared memory
object, the result is unspecified.
So, we need to check both the return value of ftruncate and
the value of errno.

g++: change in templates in gcc-4
Hey, question.. Just wondering if gcc is supposed to behave this way now.
For example, I have a template:
template class foo
{
...
void method1(T a1) {...}
T method2() {...}
...
};
Notice, method1 accepts a parameter of type T and method2 returns a
value of type T.
Well, if foo is instantiated as foo then everything is fine.
However, lets say we typedef an array type and instantiate foo with it...
typedef int bar[10]; // bar is a type: int[10]
foo f;
Now, method1 is accepting an array parameter (fine), but method2 is
returning an array value (error)
In gcc-3, there was no error until you tried to call f.method2(), but in
gcc-4 it gives the error when foo is instantiated whether the
method is called or not. I used this feature intentionally in gcc-3,
but I wanted to know if it's an ANSI thing one way or another. And if
it's not ANSI compliant now, then I guess it needs to be fixed in gcc.
Thanks,
Davy

The behaviour of GCC 4 is compliant to the ANSI standard in this regard, so you will have to fix your code. For the next time, remember to provide a fully compilable testcase (for copy & paste), and to clarify what the standard says through other means (newsgroups as comp.lang.c++.moderated and comp.std.c++, tests with the Comeau online compiler, etc.) so to report issues which are more likely real GCC bugs.

--- Additional Comments From dank at kegel dot com 2005-06-18 22:45 ---
I asked the fellow who posted the original problem report to give
me the results of 'cat /proc/cpuinfo' on the affected machine.
Here it is:
vendor_id : GenuineIntel
cpu family : 6
model : 8
model name : Pentium III (Coppermine)
stepping: 10
cpu MHz : 896.153
This is the same as one of the two affected CPU types here.
The slow routine appears to be the buffer cleaning routine,
though I haven't verified this with oprofile yet.
Here's its loop:
static char cleanse_ctr;
...
while (len--) {
*(ptr++) = cleanse_ctr;
cleanse_ctr += (17 + (unsigned char) ((int) ptr & 0xF));
}
and the output of -O3 -fPIC for both gcc-2.95.3 and gcc-4.0.0:
--- gcc-2.95.3 ---

jne .L4
It's not obvious to me why the gcc-4.0.0 generated code
should be slower when run on some CPUs, if in fact it is.
Is it the fact that the loop condition is checked with
a cmp against memory instead of a flag being set by subtracting
1 from a register?
(And where's the best place to learn about how to predict

A revised patch, allowing equality and inequality comparisons against NULL, yet
retaining warnings for things like 'if ("foo" > 0)' and 'if ("foo" == "bar")'
was posted here: http://gcc.gnu.org/ml/gcc-patches/2005-06/msg01177.html
