libc6-dbg 2.8+20081027-0ubuntu9 (i386 binary) in ubuntu jaunty

 Contains unstripped shared libraries.
 This package is provided primarily to provide a backtrace with
 names in a debugger, which makes it somewhat easier to interpret core
 dumps. The libraries are installed in /usr/lib/debug and can be
 used by placing that directory in LD_LIBRARY_PATH.
 Most people will not need this package.
