I do not recommend that you do that at all.  For one thing, malloc() will
not call _di_IHelpManager's constructor, so the _di_IHelpManager instance
will remain uninitialized and you will have undefined behavior when you try
to use it.

Where is WinHelpTester declared?

Again, there should not be any reason for the error to begin with, since
there is a public Release(void) method inherited from IUnknown.
