[Bug libstdc++/13205] New: 64BIT: Segmentation fault in code executed inside std::locale::_Impl::_M_install_facet()

["skasapin at ca dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following testcase executes with SEGFAULT in 64-bit mode:

t.C
---
#include <locale>

using namespace std;

struct MyfacetA : public locale::facet {
        static locale::id id;
};
locale::id MyfacetA::id;

int main()
{
        locale loc;
        locale loc2 = locale(loc, new MyfacetA);
        return 0;
}
