--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
The code example looks invalid for several reasons, but the following is a
simplified example that is free of library dependencies and ICEs as well:
//-----------------
template<class T>
struct A
{
template<class>
static constexpr bool is_ok = true;
template<bool v = is_ok<T>>
A(T) { }
};
A<int> p(42);
//-----------------
For gcc 5.0.0 20141115 (experimental) using the flags
-Wall -Wextra -std=c++1y -pedantic
I get:
