             Bug #: 56449
           Summary: operator-> in a template class can lead to infinite
                    template instantiation
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: basil@list.ru


Code example:

template<class T> struct Loop { Loop<T*> operator->(); };
Loop<int> i, j = i->something;

The compiler doesn't diagnose infinite Loop<> instantiation. Even CLI option
ftemplate-depth=n doesn't help.
