Just a bit more info, the crash is happening in spu_loader/spucopy.c, 
crSPUCopyDispatchTable().
In the first for-loop, the assignment temp = dst->copy_of->copyList sets 
temp to 0x1, which is later used as temp->copy.

#0  0x5557f040 in crSPUCopyDispatchTable (dst=0x80d62c0, src=0x817d8c8) 
at spucopy.c:630
630                             if (temp->copy == dst)
(gdb) bt

$2 = (struct _spu_dispatch_table *) 0xffffa520
