Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Description of problem:

While running testsuite 029 of pcp-gui testsuite, /var/lib/pcp-gui/testsuite/src/qmc_event/qmc_event dies of SIGSEGV.

Program terminated with signal 11, Segmentation fault.

Happens on all arches, with and without FIPS enabled. Abrt report is attached, or you can inspect e.g. on ibm-p730-01-lp2.lab.bos.redhat.com (root/redhat) - but I was able to reproduce it as often as I tried.

Version-Release number of selected component (if applicable):

pcp-3.8.10-6.el7
pcp-gui-1.5.11-3.el7


How reproducible:

Always.


Steps to Reproduce:
1. install pcp-gui-testsuite (and its requirements, like Xserver...)
2. cd /var/lib/pcp-gui/testsuite && ./check 029


Actual results:

Test case fails, qmc_event binary segfaults.


Expected results:


Additional info:

This is the same issue discussed elsewhere - missing sample PMDA.  The test code needs to be made more robust in the absence of this component, but ultimately it is a test-code failure, not a failure of the code being tested.

As you suggested in https://bugzilla.redhat.com/show_bug.cgi?id=1067400, running /var/lib/pcp/pmdas/sample/Install before starting pcp-gui-testsuite makes 029 test case to pass.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Given an installed & running pmdasample is a documented requirement of pcp/qa (which is also nowadays checked by the testsuite), its not worth the effort to dig further into this one.
