5.3.5/5:

"If the object being deleted has incomplete class type at the point of
deletion and the complete class has a non-trivial destructor or a
deallocation function, the behavior is undefined."


If you *know* that the destructor was not called, then apparently you
have put some code in there so that you were able to recognize it -
printing something on the screen, maybe? In any case, your destructor
is not trivial and class declaration gives you only the incomplete
type for deletion. As cited above, this is undefined behavior.
Don't delete objects if their class is only forward-declared.
