+	    <p>An optimization that avoided allocation of a stack
+	    frame for some <c>case</c> expressions was introduced in
+	    OTP 21. (ERL-504/OTP-14808) It turns out that in rare
+	    circumstances, this optimization is not safe. Therefore,
+	    this optimization has been disabled.</p>
+	    <p>A similar optimization will be included in OTP 22 in a
+	    safe way.</p>
