Disallowing creation of the temporary objects

Question

While debugging crash in a multithreaded application I finally located the problem in this statement:

CSingleLock(&m_criticalSection, TRUE);

Answer 1

I don't think so.

While it's not a sensible thing to do - as you've found out with your bug - there's nothing "illegal" about the statement. The compiler has no way of knowing whether the return value from the method is "vital" or not.
