            Bug ID: 59112
           Summary: [c++1y] ICE using auto as parameter in local class
           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 on trunk:

====================
void foo()
{
  struct A
  {
    A(auto) {}
  };
}
====================

bug.cc: In function 'void foo()':
bug.cc:5:14: internal compiler error: in check_member_template, at
