Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Comment 2 Petr Pisar 2018-08-23 06:49:10 UTC 
I can reproduce it even on x86_64. The threads support is still spooky.
Comment 4 Petr Pisar 2018-08-23 07:06:09 UTC 
The threads support is known to be broken and there is no fix in sight. I recommend disabling these thread tests that are actually optional and run explicitly when building RPM package in contrast to upstream the does not run them (for the threads support immaturity).
Comment 6 Petr Pisar 2019-11-21 15:07:57 UTC 
Red Hat does not plan to fix this issue in Red Hat Enterprise Linux 7.
If this issue is critical for you, please use appropriate channels for escalating it, e.g. contact Red Hat support.
