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.
Likewise...
Confirmed.
