Bug ID: 59638
Summary: [c++1y] ICE with pointer to function that has auto as
parameter
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:
===========================================
typedef void (*f)(auto);
struct A
{
int i;
};
===========================================
bug.cc:1:23: error: template declaration of 'typedef void (* f)(auto:1)'
typedef void (*f)(auto);
^
bug.cc:5:7: error: data member 'i' cannot be a member template
int i;

Please submit a full bug report, [etc.]
Already the second error message is bogus, because i is not a template:
