Pure Virtual Function Call Error Message


Something (or some collection of things) owns an object. class A { A *pThis; public: A() : pThis(this) { } void callFoo() { pThis->foo(); // call through the pThis ptr which was initialized in the constructor } virtual void foo() In C++ an object is responsible for creating its own members, including the virtual function table. Execute the body of the base class constructor. Source

What does it mean? Now you have to select the drive where you installed the program recently. The same goes for passing a partially-constructed (or partially-destructed) object to any function that invokes virtual functions. Another object, obviously. https://support.microsoft.com/en-us/kb/125749

  3. If the situation is a little more complicated, the error will be less obvious (and the compiler is less likely to help us): // From sample program 3: AbstractShape::AbstractShape(double valuePerSquareUnit) :
  4. Here are a few suggestions:If this happens only with a specific document, it could be caused by data corruption.

Thank you very much for pointing us in the right direction (we were suspecting v-table corruption instead and going crazy trying to find the culprit code) –BlueStrat Mar 7 at 23:41 All Rights Reserved. - Privacy Policy - Terms of Use - Advertise with Us Android Apple Internet Top Apps Windows Search Sign in Welcome!

gcc 4.x produces a warning ("abstract virtual 'virtual double AbstractShape::area() const' called from constructor" for the first program, and similarly for the destructor for the second program).
