I just now adjusted the label to be "ice-on-valid-code" instead.
This seems to be a regression relative to GCC 4.8, which compiles the testcase
successfully (with -std=c++11). We began ICEing on the testcase starting with
r0-122271.
Here is a reduced testcase:
template <int> struct a { };
struct c {
template <int d> static constexpr bool condition() { return d; }
};
template<typename>
void foo() {
using A = a<c::condition<bool(true)>()>;
}
void bar() {
foo<int>();
}
