Thanks for your reply, Robert. :)

However, I had already dealt with the trap by removing it from the code.
(Yes, I know it is not recommended. Sorry for misleading you here.)

Either way, once I get past the trap, I still have another error to deal
with. It looks like this on my compiler (VC 8.0):

This only happens with the pointer-to-pointer type, serializing the
regular pointer works ok.
