Attached file demonstrates problem. The only difference between constructors of Derived class is that first one explicitly states which Base1 constructor should be called. I would expect that both cout in main() print 8. Unfortunately the first one prints 0. f I enable explicit definition of Base1 constructor it fixes the problem. If I remove virtual inheritance in Derived class definition (class Derived: public A1, public A2) it works as well. Tested also on 4.6.1 version - issue still exist. Does not exist on 3.4.4. ^ permalink raw reply [flat|nested] 5+ messages in thread
