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.

Actual results:


Expected results:


Additional info:

That's ppc, 32-bit, not ppc64 build. See the gdb line:
Starting program: /usr/lib/firefox/firefox

ppc64 build works fine, this is ppc issue only. I don't think this is a blocker as ppc is distributed as optional.

jhorak realized that ppc binary instead of ppc64 one was executed for some reason. This is quite surprising for me as well. I'm quite sure that minor arch should not be first choice on multi-arch machines. Note that it can happen that customer would have both ppc and ppc64 installed. So I think we should investigate why this happen. Or even one can for some crazy reason use 32bit executable instead of 64bit one.

Having said that I think we can ship ff erratum and resolve this one later.

Note: This bug comes from our internal QA testing, there isn't any customer case attached here. I doubt the plain ppc32 arch is actually used anywhere so we don't have any customer bug reports.

Closing as WONTFIX as actually nobody uses that. Please reopen if there's any customer request to fix that.
