Bug ID: 60187
Summary: [4.7/4.8/4.9 Regression] [c++11] ICE with parameter
pack as underlying type for enum
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++11")
triggers an ICE since GCC 4.6.0:
==================================================
template<typename... T> struct A
{
enum E : T {};
};
A<int> a;
==================================================
bug.cc: In instantiation of 'struct A<int>':
bug.cc:6:8: required from here
bug.cc:3:8: internal compiler error: in dependent_type_p, at cp/pt.c:20283

Please submit a full bug report, [etc.]
The code was correctly rejected by GCC 4.4.0
and wrongly accepted by GCC 4.4.1-4.5.3.
