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.
