First, it is customary here to put your replies below or inline the
original posts here. When in Rome....

As for your problem, you are trying to be evil. Delete must not throw.

Compare this FAQ:

http://www.parashift.com/c++-faq-lite/exceptions.html#faq-17.3

with this one:

http://www.parashift.com/c++-faq-lite/freestore-mgmt.html#faq-16.9

The same reasoning applies for why delete cannot throw.

But see this FAQ on how to overload delete with an extra parameter:
