--- Comment #1 from Michael Meissner  ---
This occurs because both fld and ff128 return the same constant (0), one using
it as a long double and the other as a _Float128.  Having a 0 constant is not
important.  If we return 1 in both functions, it will still trap.

If we change the constant so each function (fld and ff128) returns a different
value, it works.

If we suppress inlining, it works.
