------- Comment #1 from jb at gcc dot gnu dot org 2007-04-26 10:36 ------- Confirmed. It occurs also on i686-pc-linux-gnu.
My observations: - -march specific optimizations do not seem to have any effect. What does have an effect is that on i686-pc-linux-gnu I need either -march= or -msse2 or else the vectorizer is disabled. - Like you, crash occurs with -O2 and -O3, not -O1 I.e. lowest optimization that triggers the bug for me is "-O2 -msse2 -ftree-vectorize". -- jb at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jb at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2007-04-26 10:36:01 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31699
