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 Karel Klíč 2011-08-08 15:20:25 UTC 
Several problems related to debuginfo were found in the pacemaker-1.1.5-5.el6 package. These issues might affect crash analysis done by Automatic Bug Reporting Tool and its retrace server, and also prevent proper debugging of crashes via GDB.

Unused debuginfo files
----------------------
The debuginfo package contains a superfluous file with debugging symbols. This is usually caused by using %exclude in package's spec file instead of deleting the unwanted binary from the build root. This is a low priority issue, unnecessary files cause no harm except wasted space.

debuginfo path: pacemaker-debuginfo-1.1.5-5.el6.i686/usr/lib/debug/.build-id/f7/372101b8841c6daadcde2c3f0793d2ec686078
associated (missing) binary: /usr/sbin/crm_uuid
wasted disk space: 107.0 kB

No .debug_info section in a debug file
--------------------------------------
When a binary is compiled without gcc's -g option, no debugging information is generated and rpmbuild creates almost-empty debuginfo file, which cannot be used for debugging. Please fix the package build process to use $RPM_OPT_FLAGS, which include the -g option among others.

path: /usr/lib/debug/usr/libexec/lcrso/pacemaker.lcrso.debug
package: pacemaker-debuginfo-1.1.5-5.el6.i686

This issue can be investigated and tested by using eu-readelf tool from the elfutils package. Use `eu-readelf --section-headers /usr/lib/debug/usr/bin/<debuginfofile>.debug` to see if debuginfo file contains .debug_info section. It is supposed to be there.

(This bug was detected and filed by a script.)

the section is still missing:

$ eu-readelf --section-headers /usr/lib/debug/usr/libexec/lcrso/pacemaker.lcrso.debug
There are 29 section headers, starting at offset 0x3828:

Comment 13 Andrew Beekhof 2011-10-17 21:23:19 UTC 
Oh I see.  Somehow I managed to only see the first part of this bug.
We do build with -g, I wonder why the corosync plugin doesn't contain the symbols.
