--- Comment #2 from Kamil <kamil.holubicki at gmail dot com> 2012-02-09 16:46:55 UTC --- Base virtual class object is corrupted when explicitly called auto generated constructor from derived class inititalization list. 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.
