() Thread 1 looks a bit different to me this time, but the remaining threads look like copies of the first crash. This time the crash occurred while I was publishing my planner pages to xhtml. I'm aware that you won't be able to do much unless I provide a recipe to reproduce the bug. This looks impossible to me. The second crash occurred roughly 4 weeks after the first one. I run Cygwin Emacs roughly 10 h a day, so I experience one crash in like 200 h. Also, as I have to use Emacs productively at my dayjob, I won't be able to run emacs-x11 -Q for weeks in order to see if any of my customizations interfere. Please let me know if I can pull any additional knowledge from these coredumps. regards, Markus -- Markus Hoenicka http://www.mhoenicka.de AQ score 38
