            Status: UNCONFIRMED

#include <locale>
#include <stdio.h>

using namespace std;

int main(int argc, char *argv[]) {

  locale oGlobalLocale;

  if (!has_facet< num_get<char, istreambuf_iterator<char, char_traits<char>=
 > >
>( oGlobalLocale ))
    __builtin_abort ();
}

g++ t.cpp -o t && ./t   -> works as expected
g++ t.cpp -o t -mlong-double-64 && ./t   -> aborts=
