I haven't used valgrind before, but it actually seems to hint to the problem:
vex x86->IR: unhandled instruction bytes: 0x66 0xF 0x61 0xC2
==16881== valgrind: Unrecognised instruction at address 0x8791031.
==16881== at 0x8791031: ??? (audio_convert.asm:387)
And, indeed, after compiling ffmpeg with --disable-yasm everything is fine
again.

It seems that something like that might be the case with my AMD Athlon XP.
Is that enough information to fix the bug or shall I provide further
information?
