I have compiled my system with -O3 using GCC 4.3.3 compiled with -O2 (i.e., the very GCC was compiled with -O2) and everything went OK (exact CFLAGS: -pipe -O3 -march=athlon64 -mmmx -msse -msse2 -fomit-frame-pointer). However, when I updated my USE flags, forcing the new -O3 GCC to recompile ffmpeg, at some stage I got an internal compiler error. Changing the CFLAGS to -O2 and recompiling GCC helped. Reproducible: Always Steps to Reproduce: 1. Compile sys-devel/gcc-4.3.3-r1 with -O3. 2. Compile media-video/ffmpeg-0.5-r1 with -O3 Actual Results: ffmpeg-0.5-r1 doesn't compile, you get internal compiler error at some stage Expected Results: clear compilation The machine is an x86_64-pc-linux-gnu, make was running with -j3 because the processor is dual core. Nothing else of importance.
Please re-merge gcc and try again. If it still fails, you can re-open this bug. *** This bug has been marked as a duplicate of bug 262567 ***
