            Bug ID: 59114
           Summary: [c++1y] ICE using auto in conversion operator
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet (compiled with "-std=c++1y") triggers an ICE
since GCC 4.8.0:

=======================================
template<int> struct A
{
  template<typename T> operator T();
};

void foo()
{
  A<0>().operator auto();
}
=======================================

bug.cc: In function 'void foo()':
bug.cc:8:24: internal compiler error: in push_access_scope, at cp/pt.c:220
   A<0>().operator auto();
