Red Hat Bugzilla – Bug 729038
Invalid symbolic link in debuginfo package
Last modified: 2017-01-09 11:22:55 EST
A problem related to debuginfo was found in the gnuplot-4.2.6-2.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.
Debuginfo package includes a symbolic link to each binary that has the debugging symbols stored there. For gnuplot, one symbolic link does not point to the right binary, and that makes it impossible to use build ids from a coredump to get a list of packages required by it. Usually, this is a packaging error caused usually by placing identical binary into several locations instead of creating a symlink. If one copy of the binary is SUID/SGID, it is not possible to use symlink. You can add a dependency on bug #727872 and rebuild gnuplot when that bug is fixed.
affected binary: /usr/bin/gnuplot-minimal
affected package: gnuplot-minimal-4.2.6-2.el6.i686
referenced binary: /usr/bin/gnuplot-wx
referenced package: gnuplot-4.2.6-2.el6.i686
debuginfo symlink: /usr/lib/debug/.build-id/b7/59f70c6c7cdfb867359194eeb0100d62942173
This issue has been solved in Fedora by /usr/lib/rpm/find-debuginfo.sh creating additional symlinks for identical binaries. However, symlinks should be used instead of duplicating a binary when possible.
