Building with -fno-omit-frame-pointer is not and never will be supported by upstream, even if it works the speed cost currently is significant even for x86_64. Nevertheless MPlayer SVN r30160 should have fixed it.
Mart, does it work for you when leaving out -fno-omit-frame-pointer?
I will have to test it sometime after 4th January. Leaving out -fno-omit-frame-pointer is completely out of the question for me. Profiling performance is rendered impossible if I don't pass it. Also, the default on many architectures and compiler versions does not include -fomit-frame-pointer functionality
> Leaving out -fno-omit-frame-pointer is completely out of the question for me. > Profiling performance is rendered impossible if I don't pass it. So you are instead profiling code that possibly has little to do performance-wise with production code because it has a register less at the critical points? > Also, the default on many architectures and compiler versions does not include -fomit-frame-pointer functionality Obviously it's not required there. It definitely is for x86 though, and to a degree for x86_64 (mostly to reduce differences between x86 and x86_64 asm). If, like in this case, FFmpeg code is affected, you can however test FFmpeg and report a bug to them. And trivial cases like this one might get fixed either way. However I doubt the gentoo bugtracker is the right place to report issues with stuff that is officially not supported upstream. Though adding a warning about such flags in the ebuild might make sense (but please, don't filter them out I don't want more cases like the PIC filtering where nowadays MPlayer would compile just fine if it wasn't for the filtering rules in the ebuild breaking everything).

I am profiling the whole system every once in a while, so I have -fno-omit-frame-pointer in my global CFLAGS. mplayer is picking it up, and possibly causing the compile failure (which I have to still test, hopefully tomorrow). > > Also, the default on many architectures and compiler versions does not include -fomit-frame-pointer functionality > > Obviously it's not required there.

Frame pointers are required on all architectures for any useful sample based profiling, with e.g sysprof or oprofile. If frame pointers don't exist, these tools are not able to generate a stacktrace of the samples it gathers, and so hot spot functions do not have context and are collected in one place, so it's not possible to see what caused that function to be a bottleneck, etc. That said, I should probably omit frame pointers on my 64bit systems, because there are other issues there for getting a function trace on x86_64 systems, due to necessary interrupt captures not working well yet, so not getting a good stacktrace either way yet on amd64, but frame pointers are required on 32bit for perfect sample based profiling. > And trivial cases like this one might get fixed either way.

I am including -fno-omit-frame-pointer _globally_ downstream, so downstream should work with it. > Though adding a warning about such flags in the ebuild might make sense (but > please, don't filter them out I don't want more cases like the PIC filtering > where nowadays MPlayer would compile just fine if it wasn't for the filtering > rules in the ebuild breaking everything). Not filtering out is fine if it actually compiles and works with it in there...
well, mplayer 1.0_rc4_p20111215 now uses system ffmpeg, if anything, this should be opened against ffmpeg, closing
