I have got additional evidence that __sync_fetch_and_add does not work 
correctly.  If, for example, in this code, stressed in the testcase
12658_thread-1.cc, and using atomic operations:

  const locale&
  locale::operator=(const locale& __other) throw()
  {
    __other._M_impl->_M_add_reference();
    _M_impl->_M_remove_reference();
    _M_impl = __other._M_impl;
    return *this;
  }

I wrap everything in the locale_cons mutex then the testcase doesn't fail
anymore.
