Subject: Reproducible assertion failure in XCB
Date: Fri, 14 Jan 2011 15:01:00 -0000	[thread overview]
Message-ID: <AANLkTi=Z+UQwMAu8B=MdnZ77oO5rucbOcHkPFrPUh3+3@mail.gmail.com> (raw)

1. Start the Z server
2. Start emacs -Q
3. M-x server-start
4. M-: (while t (call-process-shell-command "date" nil t))
5. Lean on C-g

Eventually, Emacs will crash with

assertion "XLIB_SEQUENCE_COMPARE(dpy->last_request_read, <=,
dpy->request)" failed: file
"/usr/src/ports/xorg/libX11/libX11-1.3.3-1/src/libX11-1.3.3/src/xcb_io.c",
line 249, function: process_responses
Fatal error (6)Aborted (core dumped)

If Emacs doesn't crash the first time and successfully exits the loop,
repeat steps 4 and 5.
