	Emacs runtime crashes with org-indent-mode and indirect-buffer
Date: Fri, 23 Dec 2011 08:18:19 +0100

[Message part 3 (text/plain, inline)]

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.

It seems that emacs breaks due to a call to "overlay-put".

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:

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

  M-x org-indent-mode

  C-c C-x b (org-tree-to-indirect-buffer)

  C-x 0 (delete-window, the one that does not have the indirect buffer)

  tab (org-cycle, inside the indirect buffer)

No, it had nothing to do with overlay-put.  It was an assertion
violation triggered by folding a tree after widening a previously
narrowed buffer.

This is fixed in version 106726 on the trunk.
