[boost] [filesystem] static object throws

Hi,
an application of mine just suddenly crashed before entering 'main', with the 
following stacktrace:

    #5  0xb7eb7106 in __cxa_throw () from /usr/lib/libstdc++.so.5
    #6  0xb7e6ccb0 in std::__throw_runtime_error ()
        from /usr/lib/libstdc++.so.5
    #7  0xb7eb5c8e in std::locale::facet::_S_create_c_locale ()
        from /usr/lib/libstdc++.so.5
    #8  0xb7e96554 in std::locale::_Impl::_Impl ()
         from /usr/lib/libstdc++.so.5
    #9  0xb7e768e9 in std::locale::locale () from /usr/lib/libstdc++.so.5
    #10 0xb78f6922 in __static_initialization_and_destruction_0
       (__initialize_p=1, __priority=65535)
        at /space/NM/boost/libs/filesystem/src/path.cpp:29

And the line in question contains just:

29        std::locale loc("");

This is CVS as of today. The problem was that I incorrectly set the 
LC_MESSAGES environment variable. However, I think that exception from static 
object is not so good idea. I can't catch it, so the error reporting just 
reads "Aborted".

Maybe, this can be converted into a function with static variable, so that the 
static variable is only initialized on the first call?

TIA,
Volodya
