The "out" parameter is not set to null so if the procedure has a bug
so that it isn't set, it will retain its previous value. Any
uninitialized variable bug can be hard to find. But a pointer is
especially hard, and in fact most pointers are automatically
initialized to null, which helps a lot. Here the "out" parameter
pointer in fact points to an internally correct data structure, just
the wrong one, or one that might have been deallocated. I think such
a bug might take a while to track down.
