--- Comment #6 from Adam D. Ruppe <[email protected]> --- And I hit it AGAIN today because in the interface, I wrote the wrong return type and used the right type in the class. The compiler SHOULD have said "original one not implemented" and drew my attention to it. Instead, it just randomly crashed with a null vtable entry. --
