Bug ID: 63730
Summary: C++11 ICE REGRESSION mangling template alias into
function template
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eric.niebler at gmail dot com
Compile this:
template <class T>
using identity_t = T;
template <template <class> class It>
void test() {
}
int main() {
test<identity_t>();
}
For me, with gcc 4.9.2, command-line "g++ -std=gnu++11 -c test.cpp", I get:
test.cpp: In instantiation of ‘void test() [with It = identity_t]’:
test.cpp:12:22: required from here
test.cpp:6:6: internal compiler error: in write_name, at cp/mangle.c:800
void test()
^
test.cpp:6:6: internal compiler error: Aborted
g++: internal compiler error: Aborted (program cc1plus)
Please submit a full bug report,

It worked on gcc 4.9.0, but started failing in 4.9.1.
