valgrind test will try to load debug information for the modules present in a stack trace. If it fails to do it, we endup with a stack trace with only memory addresses. We install debuginfo for all installed packages and look for all libs in the system common locations, and try to install the corresponding debug information package. These are acomplished with debuginfo-install yum utility script. MozReview-Commit-ID: 76mHOUKKJud
