> This looks like PR879. Will you try to build with -D__NO_MATH_INLINES and check, whether the assertion still exists?

you are right: a build with -D__NO_MATH_INLINES does not trigger that assertion.
Instead it triggers this one later on:

llvm-convert.cpp:4243: static llvm::Constant* TreeConstantToLLVM::Convert(tree_node*):
	Assertion `((__extension__ ({ const tree __t = (exp); char const __c = tree_code_type[(int)
	(((enum tree_code) (__t)->common.code))]; if (!((__c) != tcc_type)) tree_class_check_failed
	(__t, tcc_type, "../../gcc.llvm.master/gcc/llvm-convert.cpp", 4243, __FUNCTION__); __t; })
	->common.constant_flag) || ((enum tree_code) (exp)->common.code) == STRING_CST) &&
	"Isn't a constant!"' failed.

libgfortran/intrinsics/selected_int_kind.f90: In function 'selected_int_kind':
libgfortran/intrinsics/selected_int_kind.f90:22: internal compiler error: Aborted

Best wishes,

Duncan.
