Comment 2 Alexandre Oliva 2012-01-10 19:02:31 UTC 
Thanks for the bug report.  This is already fixed in today's upstream tree towards GCC 4.7, so it will be fixed in rawhide when Jakub pulls the next snapshot.  I suggest using the more standard compile flag -O2 for now, and even after the next GCC build, unless there's actual evidence that -O3 generates better code for this specific package.  The expensive optimizations enabled by -O3 can sometimes make the resulting code somewhat worse.
Comment 3 Jakub Jelinek 2012-01-12 23:54:02 UTC 
Should be fixed in gcc-4.7.0-0.6.fc17.
