 Reporter:  andysem           |       Owner:  bemandawes
     Type:  Bugs              |      Status:  new       
Milestone:  To Be Determined  |   Component:  filesystem
  Version:  Boost 1.45.0      |    Severity:  Problem   
 Keywords:                    |  
------------------------------+---------------------------------------------
 The boost::filesystem3::codecvt_error_category uses unprotected function-
 local static variable of type codecvt_error_cat, which is not POD. One
 thread may half-initialize this value when the other thread will acquire
 and use a reference to the not yet constructed error category. The object
 must be protected with call_once or a similar technique.
