we deleted an object on the heap,
and afterwards re-accessed the memory through the
dangling pointer to verify the deletion actually happened.
This works most of the time, unless the memory manager decides
to map that page differently -- in which case we just hit
random memory contents.
A better idea is thus to place this TestFrame object
into a statically allocated buffer and invoke the dtor
explicitly. This allows us to conduct the test reliably.
