--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I wonder if we should simply

--- a/gcc/cp/constexpr.c
+++ b/gcc/cp/constexpr.c
@@ -5675,6 +5675,9 @@ potential_constant_expression_1 (tree t, bool want_rval,
bool strict,
    return false;
       }

+    case CLEANUP_STMT:
+      return RECUR (CLEANUP_BODY (t), want_rval);
+
     default:
       if (objc_is_property_ref (t))
    return false;


which would also fix Bug 77545.
