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.

Spec file

It's not rpm that's crashing but something inside a script which rpm invokes during %install, based on the output that'd be inside brp-python-hardlink.

There's not a whole lot going on in brp-python-hardlink: it's a /bin/sh script which calls "find", comparing the results with "sha1sum" and calling "ln" on matches. One of those commands is segfaulting. Try adding 'ulimit -c unlimited' to the beginning of %install and see if you can catch a core dump or two, that'd tell us what exactly is crashing.

This is what I get when 'ulimit -c unlimited' added to %install section.

This log comes from task: https://beaker.engineering.redhat.com/recipes/12453#task147136

Please note, that I cannot reproduce it on RHEL6.0-Snapshot-7.

There are beaker recipes, each with 32 runs of original reproducer. None of them caught traceback.

Problem was reported against Snap-6.

Closing as it is no more reproducible since snap 7.
