Bisection points to r254437:

Instrument function exit with __builtin_unreachable in C++
Prior to that change GCC would reject the test case with a slightly better for
of an ICE:
t.C: In substitution of ‘template<class T> decltype (f(T(), "")) g(T) [with T =
int]’:
t.C:7:17: required from here
t.C:5:13: warning: ISO C++ forbids converting a string constant to ‘char*’
[-Wwrite-strings]
decltype (f (T (), "")) g (T) { }
~~^~~~~~~~~~
t.C: In instantiation of ‘decltype (f(T(), "")) g(T) [with T = int]’:
t.C:5:25: sorry, unimplemented: string literal in function template signature
decltype (f (T (), "")) g (T) { }
^
