Subject: bug#4737: 23.1.50; C-j in *scratch* after a hash table constant errors with void-function 
Date: Fri, 16 Oct 2009 15:40:12 +0100

Hello!

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In *scratch*: 

(progn
  (setq print-length nil)
  (make-hash-table)) 
=> #s(hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 data ())

#s(hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 data
 ())
=> 
Debugger entered--Lisp error: (void-function hash-table)
  (hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 data nil)
  eval((hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 data nil))
  eval-last-sexp-1(t)
  eval-last-sexp(t)
  eval-print-last-sexp()
  call-interactively(eval-print-last-sexp nil nil)

However, this succeeds: 

(car (list
      #s(hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 data ())))
=> #s(hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 data ())

XEmacs handles the problem in #'forward-sexp, details here: 

http://hg.debian.org/hg/xemacs/xemacs/file/a27de91ae83c/lisp/lisp.el#l55

When I use the XEmacs version of #'forward-sexp, the problem goes away. 

Goodbye, 

Aidan
