Looks like a dupe of bug 290741 - a different file, but the same error.
*** This bug has been marked as a duplicate of bug 290741 ***
This is not a duplicate, 290741 is about a compiler bug where the compiler manages to confuse itself due to inlining. This however is code we cannot reasonably expect gcc to compile, plus it is relatively easy to fix without any real hacks.

Well, I actually missed that one and only saw the lpc_mmx.c one. Still, one is in the qpel4 and the other in the qpel8 function. The one this bug is about (in the qpel8 function) is fixed in upstream FFmpeg, the qpel4 one from the other bug _maybe_ also (but then quite some time ago already), whereas there is no easy fix for the lpc_mmx.c one.
reopening then; what woud you suggest ? I'm seriously considering masking the pic useflag on x86 considering how gcc is broken with ffmpeg's inline asm.
Well, a lot of these bugs are things that can and should be fixed upstream, so I welcome people doing this kind of testing. One way to reduce the frequency of this kind of thing would be to make sure to have one or more FATE (http://fate.multimedia.cx) configurations testing x86+pic so it should always work on at least some compiler versions. Apart from that, adding a warning to the ebuild that suggests recompiling with -pic might be a good idea.
i dont see how re-opening this bug matters. the dupe is still open and is the same issue. x86 has limited registers and using a lot of inline assembly will not work very well with it. *** This bug has been marked as a duplicate of bug 290741 ***
Whatever you want - I just didn't consider making this a duplicate as helpful. This bug can be resolved by updating FFmpeg to a newer version, to solve the other bug (in addition) a different compiler version must be used.
