Hi I don't know what's real cause of the bug, the emacs, or the org-mode. The bug looks like this: when I edit org file, then type or use the menu to trigger global cycling function, the emacs sometimes will crash with an error message: Fatal error (11)Segmentation fault It happens frequently when the cursor is located at non-header text. It seems that if I change the cursor position into some places such as the start of the document, it never crashes. I'm using emacs-snapshot in debian lenny, with Linux kernel 2.6.31. And the org-mode is checked out from git repository. Both latest version of org-mode and 6.33 have the bug. Thanks -- Wentao Zheng
