Bug due to org-startup-indented

Hi!

When org-startup-indented is set to true I get a fatal error when using
'org-tree-to-indirect-buffer' on a heading then using org-cycle on the same
heading in the indirect-buffer.

This bug exists in org-version 7.7 & 7.8.02 in  emacs 24.0.92.1 on windows.

The following commands should reproduce the error:

M-: (setq org-startup-indented t)

"open an org-mode file with some headlines and text."

C-c C-x b
C-x 0
tab

Anyone got any ideas on how to fix this?

Regards
Gustav

I cannot reproduce this on 7.8.02. Does it happen with "-q"? Does it
happen on every Org file?

Also, what is the error reported (with M-x toggle-debug-on-error)?

Yes, unfortunately it also breaks with "-q". Using "toggle-debug-on-error"
does not work since emacs fails. It's not reporting any error before this
failure.

I've tried to debug what happens with "debug-on-entry" when calling
"org-cycle". What I find is that after a call to "overlay-put" the program
breaks.

I've also tried the same procedure without enabling "org-startup-indented"
and then nothing bad happens. This single change in emacs -q results in the
reported behaviour for me.

Nicolas, are you using windows and emacs 24.0.92?

No, I'm using GNU/Linux and Emacs 24.0.92.

Anyway, if emacs crashes, whatever may be the badness of Org indent
code, the problem should be reported to the emacs devel mailing list
instead: all that we may come up with here would be a hack.

FWIW, I cannot reproduce it either (GNU Emacs 24.0.90.2
(x86_64-unknown-linux-gnu, GTK+ Version 2.22.0) of 2011-10-27 and
Org-mode version 7.8.02 (release_7.8.02.2.g490d6a)) so the Windoze part
seems essential.

I'm not sure how much of a development environment the OP has set up on
his box, but if gdb is available, running emacs under gdb and getting a
stacktrace to report to the emacs devel list seems like the best route
forward.

BTW, is there no error message at all? emacs just dies?

Emacs crashes. It prompts with a question to attach gdb to debug. Not much
more, sorry to say. I'm not used to gdb though, so getting a trace for the
error was to big a task a.t.m.

This should be reproducible in windows using the same emacs-version though.
So I'll make sure to send a mail to emacs-devel.

Don't bother about attaching gdb etc and Don't use emacs-devel.

I suggest that you file a bug report - M-x report-emacs-bug RET - with a
simple reproducible recipe. Remember to mention in the subject that it
is a crash in Emacs *runtime*.

If the bug is at all reproducible, someone will reproduce the bug for
you and check-in a fix in no time.

Gustav did so and Eli is on this bug.  Thanks Gustav for taking 
care of reporting it there!
