     Type:  Bugs                                 |      Status:  new          
Milestone:  Boost 1.41.0                         |   Component:  serialization
  Version:  Boost 1.40.0                         |    Severity:  Problem      
 Keywords:  serialization memory leak            |  
-------------------------------------------------+--------------------------
 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.
