RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description fujiwara 2017-11-06 08:12:27 UTC
GNOME Wayland causes a SEGV:

#0  0x00007fbfbcaf2501 in __strstr_sse2 () at /lib64/libc.so.6
#1  0x00007fbfc32ddd86 in screen_has_stereo_tree_ext (screen=0xa6d6d0)
    at compositor/compositor.c:520
#2  0x00007fbfc32ddf35 in meta_compositor_manage (compositor=0x2472a90)
    at compositor/compositor.c:586
#3  0x00007fbfc32fb694 in enable_compositor (display=0x20e7400)
    at core/display.c:476
#4  0x00007fbfc32fd989 in meta_display_open () at core/display.c:966
#5  0x00007fbfc330ef0c in meta_run () at core/main.c:649
#6  0x0000000000402c4a in main (argc=1, argv=0x7fff8dd61818) at main.c:463

It's caused by the internal patch of 0008-Add-support-for-quad-buffer-stereo.patch in RHEL 7.5

I think my box does not work with the stereo extension.
