Forgive the likely simple question ... I am using boost-1.30.2 regex library in a C++ console app and have been using VC7 to debug memory leaks through the _CrtDumpMemoryLeaks() function. It reports numerous memory leaks on the first time I use a boost::regex object, albeit relatively small leaks. For example, if I use boost::regex statsRe("^\\s+8\\s+ENVI\\s+AX4.*") there are a number of memory leaks from memory allocated in the boost::re_detail::w32_traits_base::do_init() block. I am wondering if I am doing something wrong in that no destructor gets called for these objects or if small memory leaks are to be expected when using these objects. Thanks, matt
