XEmacs 21.5.b18 (+CVS20050203)
The forward-paragraph and backward-paragraph commands now fail with the
error
Invalid byte code: variable reference to constant symbol, nil.
This just began since the recent mega patch that included paragraph.el
Other motion commands do seem to work and the companion sexp movements still
work.
I know how to get debug in a function I have displayed, but how do I debug a
funtion that only works in a non-lisp (text-mode) buffer?

I wrote the following a few minutes ago, then remembered how to get
debugging to work. When StackTrace on Error is set, the function does not
fail. So I think this is a ByteCompiler error.
Any suggestions for continued troubleshooting?

It appears to be the let and let* forms that are being miscompiled. Try
byte-compiling this:
(defun some-function ()
"Docstring."
(let ((some-var 0))
t))
For me, this produces the following in *Compile-Log-Show*:
Compiling file /tmp/paragraphs.el at Tue Feb 8 09:15:20 2005
While compiling some-function:
** variable some-var bound but not referenced
While compiling some-function:
!! Invalid byte code (("variable reference to constant symbol" nil))
I'll try to look at this later today if nobody beats me to it.

I'm using CVS-20050202, native win32. I don't see any of these problems.

Compiling the *scratch* buffer (byte-compile-buffer) with your example gives
me the same error on Mac OSX. The problem may be related to a variable
multiple-lines which is no longer used but which is in the let statement at
line 241. I will try this patch:
diff -U0 -r1.10 paragraphs.el
--- lisp/paragraphs.el 2005/02/03 21:27:59 1.10
+++ lisp/paragraphs.el 2005/02/08 16:22:30
＠＠ -39,0 +40,2 ＠＠
+(require 'easy-mmode)

＠＠ -239 +241 ＠＠
- (let (multiple-lines)

＠＠ -244,2 +246,2 ＠＠
- (unless (= (point) start)

+ ;; (unless (= (point) start)

No dice, the error persists. Simply loading the source file fixes the
error as does "instrumenting the function for debugging."
