{
    // Qt 4.5 compatibility
    // this function is broken by design, so it was replaced with internalSafetyCheckAdd2
    //
    // it's broken because we tracked the pointers added and
    // removed from QSharedPointer, converted to void*.
    // That is, this is supposed to track the "top-of-object" pointer in
    // case of multiple inheritance.
    //
    // However, it doesn't work well in some compilers:
    // if you create an object with a class of type A and the last reference
    // is dropped of type B, then the value passed to internalSafetyCheckRemove could
    // be different than was added. That would leave dangling addresses.
    //
    // So instead, we track the pointer by the d-pointer instead.
