            Bug ID: 98574
           Summary: i965_dri.so segfaults, issue between 71cc1e and d2861d
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: sergio.callegari at gmail.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

Seen on Ubuntu Xenial (kubuntu) with the Oibaf ppa that provides mesa from
latest git.

Issue prevents X from starting since either the session manager sddm or kde die
when i965_dri.so segfaults. E.g.:

 traps: sddm-greeter[6763] general protection ip:7fb6b6517e79 sp:7ffdeb7eda80
error:0 in i965_dri.so[7fb6b624b000+690000]

or

 traps: ksplashqml[7098] general protection ip:7efc779ebe79 sp:7ffecc4b8a20
error:0 in i965_dri.so[7efc7771f000+690000]

issue appeared in between 71cc1e188d52bebe86a1ac72fe90f4e2a7e76778
and d2861d682a235993844989f7742c9539c3e10245

Cannot bisect better, because I'm trying packages from the oibaf repo and only
a couple of commits a day are built there.
