Subject: bug#28268: 26.0.50; (MS Windows) crash on C-g after closing Git GUI
Date: Mon, 28 Aug 2017 22:10:56 +0100 [thread overview]
Message-ID: <CAPM58oj8cj--6iK-7HHF4XKj66w9-TontjA1e90F_wR==iXZ8Q@mail.gmail.com> (raw)
Emacs sometimes crashes when I type C-g just after closing a process.
I've only seen this happen after the following recipe using Magit on MS
Windows. (Not sure whether or not Magit is essential.)
Recipe:
Visit a git repo.
C-x g ; magit-status
! g ; magit-run-popup, magit-run-git-gui
;; A nasty-looking window pops up (Git GUI, I presume). Close it.
C-g ; Crashes.
The crash is a SIGTRAP and the stack trace of the faulting thread is
as follows:
