[Sbcl-devel] type checking bug?

[John K. <jk2...@ya...>]

I ran into what seems to be a bug in sbcl 
0.8.6 on Mac OS X 10.3.2

I had defined a structure as follows

(defstruct field 
   (name :un-named)
   (ra 0d0)
   (dec 0d0)
   (x0 0d0)
   (y0 0d0))

which I changed to 

(defstruct (field (:constructor %make-field))
   (name :un-named)
   (ra 0d0)
   (dec 0d0)
   (x0 0d0)
   (y0 0d0))

because I had a 2nd make-field function that did
something completely different, and returned NIL.

Now when calling the 2nd make-field function from
the repl, I get the error that make-field did not
return a FIELD.

After (unintern 'make-field) and re-loading the 
lisp source file, all is well.

Apologies if this has been solved already.
