#5257: Concurrent posix_time streaming crashes
-----------------------------------------------------------+----------------

     Type:  Bugs                                           |      Status:  new       
Milestone:  Boost 1.47.0                                   |   Component:  date_time 
  Version:  Boost 1.45.0                                   |    Severity:  Problem   
 Keywords:  posix_time ptime ostream imbue MinGW-32 crash  |  
-----------------------------------------------------------+----------------
 The attached program crashes under MinGW-32 gcc-4.4, (but works under
 VC8).

 It does concurrent streaming of posix_time::ptime values to independent
 std::ostringstream objects.

 Mutexing the ostringstream from construction to destruction keeps it
 from crashing, but that shouldn't have to be done for independent
 streams. Mutexing just the ptime insertions makes it run longer, but it
 still crashes. And removing concurrency (i.e., running just one thread)
 allows it to run.
