 '''convert_aux''' fails in global scope:[[BR]]

 Trying to initialize global path variable by concatenating '/' a wide
 string path w/ narrow string path fails! [[BR]]

 "Unhandled exception at 0x0f8bc688 (msvcp100d.dll) in paths.exe:
 0xC0000005: Access violation reading location 0x00000000."
 [[BR]]

 If initializing inside main() scope everything works fine. I think this
 worked as expected in previous version(s) 1.48.. no luck with 1.49 though
 :( [[BR]]

 Additional info: WIN 32 and 64 bit, MSVS2010[[BR]]
 {{{
 #include <iostream>
 #include <boost/filesystem.hpp>

 using namespace boost::filesystem;

 path p(L"C:\\TEMP\\");
 path q(p / L"wide");  // Works!
 path r(p / "narrow"); // Breaks :(

 int _tmain(int argc, _TCHAR* argv[])
 {
     path p(L"C:\\TEMP\\");
     path q(p / L"wide");  // Works!
     path r(p / "narrow"); // Works here!

     std::cout << r.string() << std::endl;
         return 0;
 }
 }}}

 P.S. If more info is required I will reply here not by email.
