[Bug other/32358] Acovea finds bugs in GCC 4.3.0 and problems with default optimizations levels

[patrik dot hagglund at bredband dot net]

------- Comment #5 from patrik dot hagglund at bredband dot net  2007-10-07 17:44 -------
I have found two bugs using my own (unfinished/unreleased) Acovea
replacement (available upon request). Both are for -fsee.

gcc (GCC) 4.3.0 20071005 (experimental)
