   * bug fix: getting the order of arguments to
     SB-MOP:SET-FUNCALLABLE-INSTANCE-FUNCTION wrong produces a sensible error
     rather than a failed AVER.  (reported by Paul Nathan)
+  * bug fix: Parsing of &optional/&key/&rest arguments now never overwrites
+    arguments during copying on x86 and x86-64; it may still happen on other
+    platforms when there are more fixed arguments than stack slots.
