G'day all,
The following code signals an error in ABCL 1.5.0 on OS X 10.10.5.
[1] CL-USER(1): (directory (merge-pathnames (make-pathname :directory '(:relative :wild)) (user-homedir-pathname))) #<THREAD "interpreter" {590C3415}>: Debugger invoked on condition of type TYPE-ERROR The value NIL is not of type (OR PATHNAME STRING FILE-STREAM SYSTEM:JAR-STREAM SYSTEM:URL-STREAM).
Any help would be appreciated.
Thanks Mark Cox

This is an a [bug in ABCL's implementation, needing fixing][451].

As a workaround, you can use the (underdocumented) predicate SYS::PATHNAME-DIRECTORY-P) like in the following kludge:
(loop :for p :in (directory (merge-pathnames "*" (user-homedir-pathname))) :when (sys::pathname-directory-p p) :collect p)
