Stack trace of the crash
Here is a more useful stack trace of this crash, where we can see pointer->focus_client is NULL.
This issue is actually Weston trying to send axis events to clients not having any wl_pointer bound, which leads to this crash. It also happens when simply scrolling over weston-simple-shm.
This should fix it: https://patchwork.freedesktop.org/patch/82561/ Fixed by: commit ed6014a9e481772580f7eb9fc7a1200aca7aec5c Author: Jonas Ådahl <jadahl@gmail.com> Date: Thu Apr 21 10:21:48 2016 +0800 input: Don't try to send axis_source when there are no resources The focus_client pointer may be NULL here if the focused client has no pointer resources. To avoid a crash, NULL check focus client before proceeding to send the events. https://bugs.freedesktop.org/show_bug.cgi?id=94899 Signed-off-by: Jonas Ådahl <jadahl@gmail.com> Reviewed-by: Mike Blumenkrantz <zmike@osg.samsung.com> |
