struct->struct->class in C++ no constructor

[John Fine]

Can you provide a complete example?

As you described it, the constructor should be called.  But you haven't 
given enough information for anyone to duplicate the situation in which 
the constructor isn't called.

Was the definition of the constructor provided in the same compilation 
or was it external?  If provided, how do you know it wasn't called 
(possibly inlined and optimized to the point that you wouldn't know)?
