There is bogus address because this class was already disposed and Wipeout erased its contents with 0xdeadbeef. So it is being disposed twice which should not happen if dead pointer was eliminated properly.

What I would try is print out class object address and trigger an illegal write to 0x00000000 to get a stack trace. (IIRC there might be a system call to get stack trace but I am not sure ATM.)
