There are known but not admitted problems with -frepo on some platforms,
but:  you do have a bug in your code unrelated to this.

:     template <class T>
:     ostream& operator << ( ostream &os, const C<T>& c )
:     {
:       os << c;
:       return os;
:     }

This function is recursive.  It will call itself because you are doing `os
<< c' - which will call `operator << (ostream&, const C<T>&)' again, ad
infinitum.  This needs to cast `c' to something which has a different
operator <<, or somehow extract the proper data, probably with:

        os << c.v;
