Perhaps this is bad attitude on my part, but I think we should go ahead with the changes (which we know are helpful), and wait until the older problem surfaces. When it does, we can find another way to deal with it. For example, we could check for zeros in SLINE stabs, and fix them there, before they ever make it into GDB's line table structure.
