Testing =media-video/ffmpeg-4.4.1-r5 on ia64, after a lot of trial and error, I have found ALL of the following optimization passes need to be disabled in order to compile without ICE at -O2:

Can you include an example of such a failure? Also, we obviously want to report ICEs upstream, so we should do that. Wonder if there's a decent cvise alternative. For issues like this, we can cross compile and use cvise on amd64 anyway.
