I did it my message from 9.06.1999.

BTW. It is so simple. If we have not a specialization for a template
     the template will be called. 
     So if we use basic_string<>::iterator as parameter of the
     constructor and we have not a specialization for it, the slow
     template version of _S_copy_chars will be called.
