On i386 I have found that the problem is related with libx264. 
Using gdb:

Program received signal SIGBUS, Bus error.
0x29671740 in x264_add8x8_idct_avx2.skip_prologue () from

And this is the source code where the problem occurs:


 283 ===>     if (x264_encoder_encode(x4->enc, &nal, &nnal, frame? &x4->pic:
NULL, &pic_out) < 0)
 284             return AVERROR_EXTERNAL;

And this is the asm code where the problem occurs:

Dump of assembler code from 0x29671740 to 0x29671840:
===>0x29671740 <x264_add8x8_idct_avx2.skip_prologue+12488>: lds    (bad),%edi

Someone can help me to fix it?
