Hello dear Emacs developers! I recently stumbled upon an org-mode related bug when upgrading to Emacs 24 on windows (Emacs-24.0.92). The problem occurs when org-indent-mode is on in indirect buffers in an org-mode file (after using the command "org-tree-to-indirect-buffer" (C-c C-x b) on a headline with some sub-information) and org-cycle (tab) is done on the first line. This breaks my emacs. I've reasoned out that emacs crashes on the call to the c-function "overlay-put" when executing org-cycle. I however don't have and debug-trace.. sorry for that. The problem should be reproducible with the following: - Start emacs without any initial settings (runemacs.exe -q) - Open an org-mode file - M-x org-indent-mode - C-c C-x b on a heading in the file - tab My temporary fix for this is to not use org-indent-mode... Then everything (almost ) works as intended. I would however be happy if I could start using org-indent-mode again! This is also posted on the org-mode list but due to the relation to emacs-c-functions the question is moved to this forum. Regards Gustav Wikström
