BCC 5.82 global locale fail

[Duoas]

Hi all, I'm new to this particular forum.

I am using Borland C++ 5.82, and the following fails:

...
#include "utf8_locale.hpp"

const std::locale utf8_locale(        // A global object 
  std::locale::classic(),
  new duthomhas::unicode::utf8_facet
  );

int main()
  {
  wofstream outf;
  outf.imbue( utf8_locale );
  ...

But the following works just fine:

...
#include "utf8_locale.hpp"

int main()
  {
  const std::locale utf8_locale(       // A local object 
    std::locale::classic(),
    new duthomhas::unicode::utf8_facet
    );

  wofstream outf;
  outf.imbue( utf8_locale );
  ...

I admit I am still fairly new to messing with the STL locale class, but I don't understand what I did wrong above. It works fine with the default GCC library. (And I would prefer my code to be as portable as possible.)

Thank you for your time.
