[boost] regex win32 memory leaks

Hi, I am having a windows MFC app that dynamically links to the regex lib. On application shutdown the memory leak detection kicks in and diagnoses leaks in the regex dll. If I use the static lib everything seems to be fine. I have to admit that I don't have a clue what's going on. Any ideas? Thomas BTW this is vc-7.1 boost 1.31 -- Thomas Witt witt@acm.org
