[Bug libfortran/30617] recursive I/O hangs under OSX 10.3
--- Comment #12 from brooks at gcc dot gnu dot org 2007-02-07 09:10 --- (In reply to comment #7) > If I read the F2003 standrad correctly, then > your program conforms to F2003. You may want > to change this to an enhancement request. This is incorrect -- the code does not conform to F2003 either. Section 9.11, paragraph 3, says that a recursive I/O statement -- that is, one that occurs while another is in progress, such as the "print *, 'test'" in this code -- may not identify an external unit, unless it is a "child I/O statement". Section 9.5.3.7.1, paragarph 2, defines a "child I/O statement" as one that's occuring within a user-defined derived-type I/O function -- which is definitely not applicable here. Therefore, I believe that this bug should be closed as INVALID, but given the amount of commentary (and the fact that hanging is an unfortunate response even to invalid code), I'll let someone else make that call. -- brooks at gcc dot gnu dot org changed: What|Removed |Added CC||brooks at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30617

[Bug libstdc++/17012] [DR 526] std::list's function, remove, looks like it is reading memory that has been freed.
--- Comment #12 from hhinnant at apple dot com 2007-02-07 16:46 ---
At the ad-hoc LWG meeting in Batavia, Jan 22-24, 2007, the LWG decided that
self referencing code in list::remove must work. Here is a preview of the
issue which is currently set to become official at the Spring '07 meeting:
http://home.twcny.rr.com/hinnant/cpp_extensions/issues_preview/lwg-active.html#526
Here is a patch to mainline to make it work. I believe the approach taken by
this patch is superior to copying the value as it currently looks like a future
standard will not require that the value_type be copyable. Additionally the
cost of copying the value_type can be arbitrarily large.
If we have a utility similar to boost::address_of, that might be better than
using operator& to get the address of the value_type (to accommodate types
which overload operator&).

If they are using -Werror and insist on using -O0, then they can go ahead and specify what warnings they want to ignore, they asked for it by specifying -Werror. If documentation were enough, I'm sure there wouldnt be a warning for -Wuninitialized -O0, but there is, for obvious reasons - people generally use a build system which typically uses -Wall by default and generally people dont interface with gcc directly. - Most of the time people need to be warned - People compiling with -Werror have a closer relationship to the compiler and are better situated to deal with the warning that should be appearing for -Wall -O0. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30719

[Bug driver/30728] New: Building a 32-bit compiler on a 64-bit system should pass --32 flag to the assembler
If you configure to build a 32-bit compiler on a 64-bit Linux system with:
CC='gcc -m32' /src/trunk/configure --{target,host,build}=i686-pc-linux-gnu ...
the compiler fails because it defaults to 32-bit code but the standard
assembler is 64 bit, and it fails in building libgcc. If you are building in
such an environment, the compiler should be modified to pass --32 to the
assembler.
Note, there is the work around of putting a 32-bit assembler in the --prefix
directory so that it builds correctly, but it would be nice to have it fixed.

I agree, here's a patch to do this.
For speed reasons, we should also reverse the conversions
through the intrinsics that only make one pass through the data
(such as sum, product, or minmaxloc).

This warning seems to be wrong to me, or at least badly worded. Furthermore,
gcc should notice that the condition states "n >= 10", and n is decremented by
only 2 in each iteration, so the loop _will_ terminate. There won't be any
overflow.
It would also be nice if this warning were only printed once instead of 9
times.
