It looks like there is a problem with a buffer indeed: 0x0000000000237024 in rp_mixchunk (at=0x802800080, samples=0, buf1=0x2ab000 <error: Cannot access memory at address 0x2ab000>, buf2=0x2ab002 <error: Cannot acce ss memory at address 0x2ab002>, bufmod=4) at ../replay.c:3464 (gdb) p buf1 $21 = (int8 *) 0x2ab000 <error: Cannot access memory at address 0x2ab000> In this case, there are still 276 loops to perform but it seems we already wrote past the end of the buffer.
