You'll get this if you do the following.
;; -*- emacs-lisp -*-
(read-from-string (format "%s" (point-marker)))
This is because unlike most lisp objects, point markers can not be read
in the same syntax they print as. Babel only supports passing strings,
numbers, and lists of strings and numbers as variables between code
blocks. If you convert the point-marker to a point (integer) then it
will flow between blocks.
