You did not check whether the deallocation was actually performed as a
result of the exception. If not, P points to a valid (although not
fully initialized) object. There is also no memory leak, since you
have references to all allocated objects.

You should create your own pool and trace the calls to Allocate/
Deallocate to conclude anything useful from such a test.
