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.

Both 4.7 and 4.8 exit with a sensible diagnostic:
a.cc:2:19: error: template instantiation depth exceeds maximum of 900 (use
-ftemplate-depth= to increase the maximum) instantiating ‘Loop<T*>

= int]’
a.cc:2:19: required from here
