[Sbcl-devel] #.(SB-SYS:INT-SAP #X00000000) fell through ETYPECASE expression_[Scanned]

[Ingo Bormuth]

current sbcl fails with

#.(SB-SYS:INT-SAP #X00000000) fell through ETYPECASE expression.
Wanted one of (CHARACTER SYMBOL INTEGER).

whenever a cffi call uses a null-pointer which is defined as:

(declaim (inline null-pointer))
(defun null-pointer ()
"Construct and return a null pointer."
(sb-sys:int-sap 0))

The same code works find in sbcp-1.0.17 and clisp-2.46
but fails in sbcl-1.0.18 and 19 and todays git.

I looked around for a while but couldn't find the
blueprint. Does this ring a bell for anybody in here?

Thanks, Ingo.

Thank you very much for the quick fix
which, by the way, works as expected here!
