The following invalid code snippet triggers an ICE on the trunk:
=============================================
enum E { e };
E& operator |= (E&, const E&) = default;
=============================================
bug5.cc:3: internal compiler error: in copy_fn_p, at cp/decl.c:9717
Please submit a full bug report, [etc.]
This is related to PR38701. It's not a duplicate though, because the ICE
appeared already in July and it's not an error-recovery problem.
