I've notices something right now:

Ok, this is interesting point... Make sure that all DLLs you are using
are compiled correctly with Same MSVC runtime **DLL** (with correct import
flags) and not mixed DLL/static library/

Because if they are not, there may be more then one instance of

std::locale::_Locimp *global_locale = 0;

If it was not exported!

    foo.dll -> uses dllexported std::locale::_Locimp *global_locale
    bar.dll -> uses dllexported std::locale::_Locimp *global_locale
    baz.dll -> do not import symbol of std::locale::_Locimp *global_locale
           and uses its own version.

And you end with two static variables that are not merged... It is
very unplesant issue (which makes me love ELF and shared objects ;-) ).

When using Boost.Locale or any std::locale faces on your own
you must make sure that all DLLs and libraries same MSVC DLL. Otherwise...
wellcome to hell.
