Hi,
a.cpp: In function `void caller2()':
a.cpp:16: error: `AnyEvent::AnyEvent(const AnyEvent&)' is private
a.cpp:29: error: within this context

Why gcc requires copy constructor in such situation?

It does not require the copy constructor, just requires it be accessible. I would read the changes page for 3.4 which documents why this changed. Mainly this is required by the C++ standard.

Thanks,
Andrew Pinski
