https://svn.boost.org/trac10/ticket/7211 <p> path_locale is defined using this construct in path.cpp: </p> <p> std::locale path_locale(std::locale(), new windows_file_codecvt); </p> <p> Under the debugger of VC10/11, the destructor of std::locale calls free() for this facet pointer when refcount reaches 0. </p> <p> I ackknowledge this is a bug in dinkumware implementation of the microsoft STL.
