#3848: Boost.Exception and transporting exceptions between threads

     Type:  Bugs                                 |      Status:  new           
Milestone:                                       |   Component:  exception     
  Version:  Boost 1.40.0                         |    Severity:  Problem       
 Keywords:  exception thread safety              |  
-------------------------------------------------+--------------------------
 The attached example program exc.cc crashes from time to time.
 I suspect that the problem is that detail::error_info_container_impl is
 not thread safe.

 Here is gdb stack trace:
 Core was generated by `./exc'.
 Program terminated with signal 11, Segmentation fault.
