Warning on C++ catch by value on non primitive types

[Thomas Costa <tcosta@xxxxxxxxxxxxxxxx>]

Is there any way to get gcc/g++ to warn on C++ code that does a catch  
by value of non primitive types (i.e. types that aren't int, float,  
bool, etc.)?

I would take a warning on any catch by value but the ideal would be a  
warning that doesn't fire for "catch (const int x)"

This continually creeps into our our C++ code base.
