  Version:  Boost 1.56.0      |   Severity:  Problem

------------------------------+---------------------
 I will create a boost thread to delete some outdated files, and there is
 high possibility the program crash, when the program exit.

 I got the issue like me, but not determined. I doubt it's reason of the
 static variable of locale.
