[Bug c/28621] New: SEGSEGV at set_fast_math () at ../../gcc/config/i386/crtfastmath.c:97 when using the -Os flag

2006-08-06 Thread magsilva at gmail dot com 
After build a new version of procps using the "-Os" flag for gcc, all its
(procps) software (ps, top, etc) were failing due to a segmentation fault. I
couldn't find a report about that at Bugzilla, but I did find one at
"http://www.netdomination.org/~stkn/index.php?/archives/24-Anatomy-of-a-segfaulthtml";.
Although the author of that report was using ulibc (and I glibc), it applied
perfectly to my case. After I removed the "-ffast-math" from the procps compile
command, everything worked fine again.

I applied this patch against the gcc 4.1.1, but the bug is still there (at
least procps keeps segfaulting).

Sorry, but I didn't know that. I reported the bug against GCC 4.1.1 and the
target milestone set for it is GCC 4.1.2. So, I expected that patch to work
with gcc 4.1.x. The 'force_align_arg_pointer' attribute is available at GCC
4.1.2 or just GCC 4.2.x?

[Bug fortran/24324] New: ICE: Floating point exception

2005-10-11 Thread magsilva at gmail dot com 
I'm trying to build gcc 4.0.2 and I got an error when building the support for
the fortran language (c, c++, java, etc builds just fine). Since the problems
looks specific to fortran, I build gcc with the following configuration:

../gcc-4.0.2/configure --enable-languages=f95

The error I got is:

Thank you. I simply had no clue about what was responsable for this error. My
gmp really had a bug ('make test' failed).
