Hi, I experienced this same bug regularly running Kicad on Debian Jessie with xorg 1:7.7+7. I can supply more bug report info & stack traces if required, but I'm also pretty sure I know the cause and a potential fix.
The original upstream bug was this one #24274, which has the same symptoms (segfault in fbBresSolid): https://bugs.freedesktop.org/show_bug.cgi?id=24274 The fix for that bug caused this regression reported upstream: https://bugs.freedesktop.org/show_bug.cgi?id=54168 That regression was also reported in Debian as Debian bug #688908 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=688908 The Debian fix for the regression was to revert the upstream patch that fixed the original bug. In Debian this patch is 06_Revert-fb-reorder-Bresenham-error-correction-to-avoi.diff - regression is fixed, but the segfault comes back. Recently a commit was applied upstream (1b94fd7779) that fixes the regression (while also keeping the original segfault fixed). I've been running custom xserver-xorg 1:7.7+7 packages with the "06_Revert-fb-reorder" patch replaced by the patch from 1b94fd7779 instead, without any problems. If it's useful for the maintainers then I can attempt to send a patch to the Debian package that makes this same change. I'm pretty unfamiliar with Debian packaging which is why I'm not sending one now, but there's only one way I'll ever learn... :) Thanks everyone for their time looking into this. Please let me know if I can supply any more info at all. Angus -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
