Bug ID: 58535
Summary: [4.8/4.9 Regression] ICE with virtual template
function
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 triggers an ICE since GCC 4.8.0:
======================================
struct A
{
template<int> virtual void foo();
};
======================================
bug.cc:3:17: error: templates may not be 'virtual'
template<int> virtual void foo();
^
bug.cc:3:35: internal compiler error: in check_member_template, at
cp/decl2.c:510
template<int> virtual void foo();

Please submit a full bug report, [etc.]
A c++1y variant crashes (on trunk) without an error message before the ICE:
======================================
struct A
{
virtual void foo(auto);
};
