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.

commit 3845290458cd498e490078318ae5306911cb47a9

A NULL pointer returned by getlogin was being used to initialize a std::string object.

This problem affects systemtap releases 1.5 and 1.6.
Comment 2 Dave Brolley 2011-09-14 20:28:31 UTC 
commit e91c276f51fa85a62f8e2996ff4b94909a2a14f7 should be included in the fix for this problem. It reworks part of the server start up which was changed by commit 3845290458cd498e490078318ae5306911cb47a9.
Comment 3 Dave Brolley 2011-09-15 19:26:52 UTC 
commit ba354d3072f0df3f1581b0fba8aa7d92a16e0362 should be included in the fix for this problem. It reworks a systemtap.spec change made in commit e91c276f51fa85a62f8e2996ff4b94909a2a14f7.

Yes, a fix from git systemtap has been backported to the $FIXED_IN_VERSION
build that should be in the beta, or immediately thereafter.

Hello RH,

The fix did not make beta as i do not see any change in Systemtap packages in Beta1 release:

Starting stap-server -a "powerpc" -r "2.6.32-202.el6.ppc64" -u "stap-server"
/usr/libexec/systemtap/stap-start-server: line 51:  1816 Aborted                 ${stap_pkglibexecdir}stap-serverd "$@" < /dev/null > /dev/null 2> /dev/null
