Description Karel Klíč 2011-08-08 15:19:58 UTC 
A problem related to debuginfo was found in the less-436-4.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/less
affected package: less-436-4.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.)

Spec file patch

Spec file patch removes premature call to strip in order to successfully generate .debug files by find-debuginfo.sh
