test case for server crash
Created attachment 26091 [details] [review] proposed patch The client calls RRQueryVersion with 0.0 as version. That's all sorts of wrong, but we still shouldn't crash... *** Bug 21883 has been marked as a duplicate of this bug. *** bugzilla apparently didn't like my mail, so trying again from the web... commit 12e725d08b4cf7dbb7f09b9ec09fa1b621156ea9 Author: Julien Cristau <jcristau@debian.org> Date: Fri May 22 09:54:38 2009 +0200 randr: fix server crash in RRGetScreenInfo We don't return rates to randr < 1.1 clients, so don't allocate space for them. This fixes a FatalError due to not all allocated space being used. X.Org bug#21861 <http://bugs.freedesktop.org/show_bug.cgi?id=21861> Reported-by: Guillaume Quintin <coincoin169g@gmail.com> Signed-off-by: Julien Cristau <jcristau@debian.org> |

Created attachment 26086 [details] log file from server crash The attached program submitted by a user as part of an XCB bug report will reliably crash my X server. xdpyinfo reports xorg 1.5.99.1, and xrandr reports version 1.2. My hardware is an Intel quad-core with a 965GM IIRC. An Xorg.log is attached.
