Steven,
Thank you, I did not know about phoenix's operator capability.
Do you agree with this statement:
GetC increments the shared_ptr's reference count when it returns a
shared_ptr to operator*. After operator* dereferences, it decrements
the shared_ptr reference count. Then the function "x" is executed.
Hence nobody is holding a reference count on behalf of function "x".
Thank you again,
Chris
