State-Changed-Why:
    not a bug, but a QOI issue. I've attached a modified
    test case. See [3/6/2]/2 you have the equivalent of the
    example there, except with implicit template
    instantiations (over which you have no control).
    
    We should try and DTRT here

>Description:
In the attached program first used constructor of class A is copy constructor, i.e. copy constructor is called before any class objects are initialized (so it tries to copy uninitialized object).

The program prints which constuctor of A is called, and the output look like:

Constructor A(const A&)
Constructor A(const A&)
Constructor A(const A&)
Constructor A()
