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
