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

I've tracked down the bug and managed to write a simple testcase:
/* With GCC 4.3.2 and -O2 option: output value is 1 instead of 0.
* If -fno-strict-aliasing is added, this bug disappears.
*/
