Bug ID: 60053
Summary: [c++1y] ICE with auto as member template function
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 valid code snippet (compiled with "-std=c++1y") triggers an
ICE on trunk:
===============================================
struct A
{
void foo(auto);
};
void A::foo(auto) {}
template<typename> struct B
{
template<typename T> void bar(auto);
};
===============================================

Please submit a full bug report, [etc.]
If I just leave out the name "T" of the template parameter, the code compiles
fine. This is probably related to PR60052.
