From: "ami_stuff at o2 dot pl" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/41311] [4.5 regression] m68k - FFmpeg crashes when converting mpg to avi Date: Sat, 02 Jan 2010 00:42:00 -0000 [thread overview] Message-ID: <20100102004157.13014.qmail@sourceware.org> (raw) In-Reply-To: <bug-41311-17839@http.gcc.gnu.org/bugzilla/> ------- Comment #11 from ami_stuff at o2 dot pl 2010-01-02 00:41 ------- The problematic function is as was said "ff_rate_estimate_qscale". I found out which optimizations causes the problem: -m68020 -m68881 -O1 -fno-tree-ccp -fno-tree-dominator-opts (works ok). -m68020 -m68881 -O1 ("Abort trap") I attache output files from GCC 4.5 20091224. Maybe someone will try to create a simpler testcase for thie bug in the future. GCC 4.4 and all older versions of GCC works correctly, so bug was introduced in the GCC 4.5 branch (only for -m68020/30 -m68881, -m68040 & -m68060 seems to be OK). -- ami_stuff at o2 dot pl changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|[4.5 regression] FFmpeg |[4.5 regression] m68k - |crashes when converting mpg |FFmpeg crashes when |to avi |converting mpg to avi http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41311
