[boost] [Locale] Static locale initialisation

I'm encountering a crash with Boost.Locale as the process terminates

I initialise the global Boost.Locale in the contructor of a class with a
single static instance (the ATL module to be exact) as I don't have access
to the code of my main method (it comes from the Boost.Test runner).   A
static object seems to be the only logical place to put this code:

#include <boost/locale.hpp> // boost::locale::generator

class CModule : public ATL::CAtlModule
{
public :
    CModule() : ATL::CAtlModule()
    {
        try
        {
            // Initialise Boost.Locale translation mechanism
            generator gen;
            gen.add_messages_path("C:/My/Path");
            gen.add_messages_domain("swish");
            std::locale::global(gen("")); // default locale
        }
        catch (std::exception) {}
    }
    
    HRESULT AddCommonRGSReplacements(IRegistrarBase*) { return S_OK; }
};

CModule _AtlModule; // Global module instance

However, when I run my EXE, it crashes as it terminates with:
Unhandled exception at 0x5ba43d93 (msvcp80d.dll) in test-shell_folder.exe:
0xC0000005: Access violation reading location 0x0321f4e4.

and the following stack trace:

If I move the initialisation code to run just before each point I need to
use translate() then it works fine.  So maybe this has something to do with
the way static data is destroyed.  This is on Windows - not sure about
other platforms.

Any ideas?

Many thanks.

P.S. I realise Boost.Locale isn't in Boost yet but previous discussions
have been here so it seems a reasonable place to ask.
