Comment(by sohail):

 The sample code you post looks to be incorrect. Specifically, you can't
 cast from T* to void* and back to anything but T*. This will especially
 apply in multiple inheritance.

 I think to do anything further on this bug, a better test case needs to be
 given. Specifically one that we can compile and see failing.
