Bug ID: 58648
Summary: [c++11] ICE with variadic template
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++11") triggers an ICE
since GCC 4.4.0:
====================================================
template<int, typename...T, T...> int foo();
int i = foo<0>();
====================================================
bug.cc:3:16: internal compiler error: tree check: accessed elt 2 of tree_vec
with 1 elts in tsubst_pack_expansion, at cp/pt.c:9535
int i = foo<0>();
