Milestone:  To Be Determined  |   Component:  thread  
  Version:  Boost 1.47.0      |    Severity:  Problem 
 Keywords:  thread            |  
------------------------------+---------------------------------------------
 Since this cast to void* is used as the key in the tss data, if you delete
 a thread_specific_ptr, and then another one is allocated with the same
 address, it will reuse the value (even if it is of the wrong type).

 Attaching repro case.

 It seems like part of the issue is the design to only delete the calling
 thread's value.  Maybe it would make sense to run through a linked list
 running through the thread_data_base instances and delete associated
 values during ~thread_specific_ptr?
