 std::vector crash using with DLL?

As a guess I would say that you are not deleting the MyClass objects when
you clear the vector.
Objects within vectors are deleted via their destructors when the vector is
'clear'ed but
pointers are not.


THEDLL_API void ClearVector(vector<CMyClass *> &vect)
    CMyClass *pItem = NULL;
        pItem = vect.back();
        delete pItem;


and the calling code would be

 vector<CMyClass *> vect;
 printf("The string from the vector is %s\n", vect[0]->GetString());
 printf("Vector cleared\n");
