Subject: 23.3; cua-mode C-x not working
--text follows this line--
This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

1) emacs-q
2) M-x cua-mode
3) C-x b
4) type in some random letters to create a randomly named buffer
5) type in some random letters to create a random word in my new buffer
6) select the new word
7) C-x (expect to cut the selected text)
8) get message in mode line:
   'Symbol's function definition is void: cua--register'

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file

Thanks for the report, but I cannot reproduce this with Emacs 23.3 on
GNU/Linux. cua--register is a variable, not a function. It's hard to see
how this error could happen. It almost looks like your cua-base.el has
been mis-compiled, since the only reference to cua--register in
cua-cut-region is:

(cond
   (cua--register
    (copy-to-register cua--register start end t))
    ...)

I couldn't repro it either, and I too see nowhere the value of variable
`cua--register' being called as a function. 

Mike sent me a screenshot separately (he originally thought it was a conflict
between Icicles and CUA mode), and in the screenshot there is this error message
in buffer *Messages*:

cua-cut-region: Symbol's function definition is void: cua--register

IOW, it was indeed `cua-cut-region' that tried to invoke `cua--register' as a
function.  No idea why.

He's using the 23.3.1 release.  Dunno why I cannot repro it using the same
release.

Maybe if he byte-compiles cua-base.el anew the problem will go away...

Is this a type, and you really invoked "emacs -q"?

Can you try with "emacs -Q" (capital Q)?

I cannot reproduce this in that very binary.  C-x works as expected
for me in CUA Mode.

Could it be that you have some local customizations which cause this?

Hi Glenn,

Re-byte compiling seems to have made the issue go away
However it has been a bit random in its appearance.

Seems reasonable to to close the ticket at this time.

Thanks

Mike
