3412,Memory leak in BOOST_CLASS_EXPORT registration,Runar Undheim <r.undheim@…>,Robert Ramey,"Added example of code that will give memory leak. The code is tested with MSVC-8.0. When run in debug the program will show three memory leaks. If I set a break point in the void_caster_shortcut constructor the function is run once, but the destructor is never called.
