When I emerge mplayer it always reports Illegal instruction in init_audio_codec. It does not depend the file type I try to play. I tried divx, vidx, mpeg, and even mp3. The error occures if I give -ao null either. However if I install it from the original distfile by ./configure && make && make install, I have a fully working mplayer installed. Reproducible: Always Steps to Reproduce: 1. emerge mplayer 2. mplayer test.mp3 Actual Results: mplayer crashed with illegal instruction Expected Results: play the media file.

Well... You have 3dnow in your USE and you have a p4... Along side your CFLAGS choice of -O4... I'd have to recommend that you read the docs again. Rebuild it with features that are actually supported by your processor.
what's he trying to say is that USE=3dnow is not appropriate for pentium4's and since supports 3dnow instructions, there's probably a good chance that's the trouble once you take 3dnow out of USE, please try running `emerge world --newuse -p` and re-emerge any packages that show up also, CFLAGS=-O4 is not valid ... there is no such flag as '-O4', please use -O2 or -O3 thanks ! :)
actually, you're using portage-2.0.50 ... --newuse is a 2.0.51 option :) so once 2.0.51 is released, please use that !
