--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
ICE started with r215738, before that it was rejected:

pr80991.cpp: In function ‘void foo()’:
pr80991.cpp:3:46: error: expected primary-expression before ‘int’
   static_assert(__is_trivially_constructible(int, int), "");
                                              ^
pr80991.cpp:3:51: error: expected primary-expression before ‘int’
   static_assert(__is_trivially_constructible(int, int), "");
                                                   ^
pr80991.cpp:3:54: error: there are no arguments to
‘__is_trivially_constructible’ that depend on a template parameter, so a
declaration of ‘__is_trivially_constructible’ must be available [-fpermissive]
   static_assert(__is_trivially_constructible(int, int), "");
                                                      ^
pr80991.cpp:3:54: note: (if you use ‘-fpermissive’, G++ will accept your code,
but allowing the use of an undeclared name is deprecated)
pr80991.cpp: In instantiation of ‘void foo() [with bool <anonymous> = true]’:
pr80991.cpp:8:13:   required from here
pr80991.cpp:3:45: error: ‘__is_trivially_constructible’ was not declared in
this scope
   static_assert(__is_trivially_constructible(int, int), "");
                                             ^
