Description Karel Klíč 2011-08-08 11:19:19 EDT
A problem related to debuginfo was found in the libtar-1.2.11-16.el6 package. This issue might affect crash analysis done by Automatic Bug Reporting Tool and its retrace server, and also prevent proper debugging of crashes via GDB.

A debuginfo file for a binary is not present in the debuginfo package. This might be caused by:
 - binary being compiled without debugging information
 - debugging information being removed from the binary by a build script
 - rpmbuild failing to extract debugging information from a binary in a buildroot because of permissions (eg. suid binaries, binaries without executable flag set)

affected binary: /usr/bin/libtar
affected package: libtar-1.2.11-16.el6.i686
binary doesn't contain debug sections (it was probably stripped)
affected binary file mode: 100755

This issue can be investigated by using eu-readelf tool from the elfutils package. Use `eu-readelf --notes /path/to/binary` to get build ID of a binary. Then check that the debuginfo package does not contain /usr/lib/debug/.build-id/<aa>/<bbbbbbbb>, where <aa> are the first two chars of the build ID, and <bbbbbbbb> is the rest of it. It should be a symlink pointing back to the binary.

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

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated

appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
