I'm replying to my own message.

I see the crash trips on following movaps instruction

In function imdct_do_512_sse in liba52/imdct.c:753

0x00525b26 <imdct_do_512_sse+54>:	movaps 0xc39dd8(%esi),%xmm2

ESI = 0 and so data was not 16 byte aligned !

The 0xc39dd8 value points to
static float __attribute__((aligned(16))) sseSinCos1c[256];

but 0xc39dd8 is not aligned to 16 bytes !
