Comment:

 Boost.Regex does cache some data (mostly locale related stuff) for
 performance reasons.  This ''does'' get cleaned up at program exit, but
 depending upon when _CrtDumpMemoryLeaks() is called the data may still be
 in existance at that point giving the appearance of memory leaks.

 Other tools like Visual Leak Detector, or Valgrind are smart enough not to
 generate these false positives, and provide much better diagnostic info
 than the MS tools which IMO are next to useless for tracking issues down.

 HTH, John.
