Answer by Zan Lynx for Do all functions in a c++ program's main function get called regardless of error?

An uncaught C++ exception will terminate the program. Often with a stack trace but that is up to the implementation.

So no, in your example bar() will never be called.

Update: In some situations the optimizer could inline both functions and move some code from bar to the top of main. You would only see this in a debugger though, because anything with side effects cannot be moved like that.
