I don't know if this is related, but I also get a random crash on Windows. When it happens, it is soon after starting Emacs, on the first use of completion. I have (setq icomplete-show-matches-on-no-input t), so completion is doing a lot of work after a short delay. I have not tried disabling that to see if it helps, but I'll do that now. If I wait some time (not clear how long), I don't get a crash on completion. So there seems to be some race condition. -- -- Stephe
