--- 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:

--- Comment #4 from Arkadiusz Miskiewicz <arekm at maven dot pl> ---
Invalid system.ads was used (sparc64 version) due to local broken patch (even
on x86_64).
