 It's highly unlikely there's anything there in any mips binary, so
 it's most likely jumped through an uninitialized pointer.
 probably the best approach is to binary-search where it crashes :-/
 0x785f9f20 becomes a valid instruction if byte-swapped but that
 doesn't seem like a likely source of the bad value...
