I tested with 4.3.1 today, _with_ optimizer, and the test suite
passed. To me it looks like the problem was introduced between
4.3.1 and 4.3.2. I have to admit that this gcc 4.3.1 was itself
compiled with a little patch applied to fix some compilation
problems with glibc, so it's not a vanilla gcc. I can provide
details on this if required.
