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)
