From: Chong Yidong <cyd <at> stupidchicken.com> To: Markus Triska <markus.triska <at> gmx.at> Cc: 730-done <at> debbugs.gnu.org Subject: 23.0.60; Crash in next_element_from_display_vector Date: Sun, 17 Aug 2008 19:52:44 -0400
I've fixed the crash. Thanks for the concise and useful bug recipe. I noticed that Emacs can be somewhat slow under the given conditions (linum-mode + outline mode with hidden lines). I think this is because scanning through multiple invisible lines is an expensive operation when display elements like those added by linum mode are present. There may be a way to optimize this, but it's not clear to me right now. I'll take a look at this later, but for the moment I'm closing this bug.
