Pure virtual function call

Likely your constructor is trying to call something pure virtual, or calls something which ends up calling something that''s pure virtual, which is only defined in a subclass. When the first constructor runs, the object isn''t really set up completely. The Vtable actually changes before running each constructor. If you manage to call a virtual function before the subclass constructor runs, it won''t be doing what you expect.

As far as I know, in constructors there''s no late binding. Just early binding - thus calling virtual function in constructor ends up with calling local version. And the linker should not link application where is binding (early) to pure virtual function...

Btw - debugging shows up that it occurs in delete call - thus it is probably in destructor in which (like in constructors) there''s only early binding.

- Unreadable code is code written on a piece of paper, but not the one, in which the programmer is using a space in the place you don''t.
- Real programmers aren''t afraid of goto

I''ve had that error too, I think it was the result of some misuse of multiple inheritance. Check that all classes that need virtual inheritance are using it.
