[Openmcl-devel] should (concatenate (type-of "HTML") "HTML" "-DIRECTORY") work?

Hello,

the following fails in clozure recent sources,

? (let ((data-type-string (string :html)))
       (concatenate (type-of data-type-string) data-type-string 
"-DIRECTORY"))
 > Error: The type specifier (SIMPLE-ARRAY BASE-CHAR (4)) is not 
determinably a subtype of the type (VECTOR CHARACTER 14)
 > While executing: MAKE-SEQUENCE, in process Listener(3).
 > Type cmd-. to abort, cmd-\ for a list of available restarts.
 > Type :? for other options.
1 > (lisp-implementation-version)
"Version 1.6-r14489M  (DarwinX8664)"

Is this an incorrect assumption in the code or an error in clozure.

This causes current cl-http to fail while compiling in clozure 1.6.

saludos

Karsten
