Is egrep the one segfaulting? You can do the same as before to build
a "grep" deb with debugging symbols, then just dpkg -i
../grep_....deb. apt-get {--re,}install grep later if you wish.
It isn't completely clear to me how gdb would handle debugging the
grep; you might have to change the shell script to use
'gdb egrep "$1" $DPKGLIST'
instead, or just dump "$1" and $DPKGLIST to a file to fiddle with it
manually.
