A while back a patch was sent out for make-bitmap, with the :storage keys for
rref/rset explicitly defined to be :pointer. However the same problem occurs
in various other situations:
? (setq bm (make-bitmap 0 0 10 10))
#<A Mac Zone Pointer Size 34 #x2C425C>
? (rref bm :bitmap.bounds)
> Error: Illegal attempt to get a pointer to a :RECT within a handle
> While executing: CCL::EXPAND-HANDLE-RECORD-GET
> Type Command-. to abort.
See the RestartsI menu item for further choices.

and the results returned from (copy-record bm :bitmap) contains garbage values.
Could the problem instead be in interfaces;QUICKDRAW.lisp where
(defrecord (BitMap :handle)
(baseAddr :pointer)
(rowBytes :signed-integer)
(bounds :rect)
)
should be defined as
(defrecord (BitMap :pointer)
(baseAddr :pointer)
(rowBytes :signed-integer)
(bounds :rect)
)
?
Incedently, (copy-record) fails to work if the optional record-type argument
is not provided:
? (copy-record bm)
> Error: Too few arguments in NIL.
> While executing: COPY-RECORD
> Type Command-. to abort.
See the RestartsI menu item for further choices.

And for anyone who is doing source patches (from p1&2 etc.), it might be
useful to include in the patch release notes instructions to do
(reindex-interfaces)
after completeing the patches.
