debug 2 causes alien code to be compiled badly

[Nikodemus Siivola]

The first one gives a compiler note about %SAP-ALIEN -- you know, the one that indicates horrible performance loss. The second one doesn't.

(locally (declare (optimize (debug 2)))
  (sb-alien:define-alien-routine ("execv" sys-execv1) sb-alien:int
    (program sb-alien:c-string)
    (argv (* sb-alien:c-string))))

(locally (declare (optimize (debug 1)))
  (sb-alien:define-alien-routine ("execv" sys-execv2) sb-alien:int
    (program sb-alien:c-string)
    (argv (* sb-alien:c-string))))
