--- Comment #1 from Zdenek Sojka <zsojka at seznam dot cz> 2011-02-16 22:36:17 UTC --- "-ftree-loop-if-convert -fno-tree-reassoc -fno-tree-vectorize" gives about 316 exec failures on current trunk. I should try the fix for PR46029 from http://gcc.gnu.org/ml/gcc-patches/2010-11/msg01613.html, but I am failing to apply it (I can't find the revision it applies to, and the mentioned 0001-Fix-PR46029-reimplement-if-convert-stores.patch in general).
