With 4.0 and -fnew-ra, we just seg fault (I think this is why we should remove -fnew-ra on the mainline because it does not work on most programs at all). -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed| |1 Last reconfirmed|0000-00-00 00:00:00 |2005-01-15 21:04:44 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19464
