[1.49][filesystem] problem while instantiating a global bfs::path variable
Hello, using a global path variable as in the following sample is no longer possible when using 1.49 under Windows: #include <iostream> #include <boost/filesystem.hpp> boost::filesystem::path global_path("."); int main() { std::cout << global_path << std::endl; return 0; } The program crashes while starting. The following backtrace was captured:

The program was built using boost 1.49 under Windows 7 and MSVC 10. The same sample works as expected using Boost 1.48 while keeping the rest untouched. Thanks for clarification, Jan.
