Bug#309210: gcc-4.0 miscompile PARI/GP on x86

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Package: gcc-4.0
Version: 4.0.0-7
Severity: normal

Hello Debian GCC maintainers,

gcc-4.0 and gcc-snapshot generate wrong code for PARI/GP 2.2.10 on x86.
The source code can be found here:
<http://pari.math.u-bordeaux.fr/pub/pari/unstable/pari-2.2.10.alpha.tar.gz>

The problem is in the file src/basemath/alglin1.c, function ker0().

The compilation command used was:
gcc-4.0  -c -O3 -DGCC_INLINE -Wall -fno-strict-aliasing -fomit-frame-pointer -DBOTH_GNUPLOT_AND_X11 -I. -I../src/headers  -o alglin1.o alglin1.i

Please find the preprocessed source here:

Cheers,

Imagine a large red swirl here.
