Hello, The changes made to filesystem/v3/src/path.cpp between v1.48 and v1.49 seem to be causing a crash if I initialise a path as e.g. a global variable or as a static class member, but only for a Debug build. (I'm using VS10 on 64-bit Win 7). The following program exhibits this behaviour: |#include "boost/filesystem/v3/path.hpp" boost::filesystem::path p("p"); int main() { return 0; } | In Debug, I can see that the third path constructor calls |codecvt()|, which calls |wchar_t_codecvt_facet()|, which returns |codecvt_facet|. However, |codecvt_facet| hasn't been initialised at this point. This appears to only be the case for Debug builds though. I'm unclear as to whether this is an MSVC bug though. I thought that the Standard required |codecvt_facet| to have been initialised before |wchar_t_codecvt_facet()| since it comes earlier in the same translation unit. Could someone please clarify whether I should file a bug report with boost please? Thanks, Fraser.
