        Wow. I made something crash windows 98. Let me put another notch
in my belt.....

        Okay, right now, for xapobjs, the only crash-casuing bugs I can
really think of are those having to do with freeing a unique object ->
        This is because i set the strings without allocating memory for
them... which is what we call a 'bad thing'.  Look through the section of
the code for the line like obj->sdesc="Undefined" .. and use str_dup or
the like instead.

        Now, as for crashing upon xapobj load, I'm sure I wrote to the
list what that bug was, but I can't for the life of me remember, since
that was several working revisions ago (well, for me).  I would do the
following though:

        Check and make sure that the object _should_ be saved.. ie, a
corpse may be saved, however, since it is not set as a unique object,
you're going to get a line like:

0 0 0 0 0 0

        In your rent file... this should only result in loading a bug
object though - in most situations.  Maybe not.. who knows.  I recommend
that you check the criteria for saving an object - only save -1 objects if
they're flagged unique, etc... make sure that's all correct...

        You should be able to check this very easily in your code, since
the rent files are ascii :)

        As well, check the loading code, and make sure that there are no
infinite loops, as my original version did have a few of those, and I did
skip around alot, I may have left a case out...log() messages are good for

        Since you know when it happens though, run the mud through the
debugger... you may get a good crash then.. else, log it to a file, and
pick up the logs when you're done rebooting :)

        I'll have a new version out sometime at the end of next week I
think, been busy at work re-securing after a break in on the systems.
