Package: gcc-4.3
Version: 4.3.2-1.1
Severity: important
Tags: lenny

When I build GMP 4.3.0 with gcc 4.3.2, I get the following errors in
"make check":

rootrem.c:338: GNU MP assertion failed: bn >= qn
/bin/sh: line 4:  2231 Aborted                 (core dumped) ${dir}$tst
FAIL: reuse
rootrem.c:338: GNU MP assertion failed: bn >= qn
/bin/sh: line 4:  2256 Aborted                 (core dumped) ${dir}$tst
FAIL: t-root

This is a known bug in GCC 4.3.2 (I don't have any reference for the
moment, but I can ask for more information), that has been fixed in
GCC 4.3.3. I wonder if the patch can be backported to lenny, as such
bugs (compiler bugs which silently lead to incorrect code) can have
nasty effects on software the user or administrator has compiled:
incorrect results, erratic behavior...
