Most things in circle which have multiple strings which are exactly the same
share a common pointer to a single character string - saving oodles of ram.
Because of this, if you fiddle the pointed at text, everything which uses it
will also be fiddled.  If you use str_dup() to duplicate the text you want
attached to whatever it is you're stringing, it will automagically allocate
enough space for your new string, and point to it - leaving the original
string which (most likely) has a lot of things pointing to it, untouched.
i.e. This should work fine for you, in place of however you were trying to
copy your data into the "strung" field...

obj->short_description = str_dup(arg);

On a side note - has anyone considered prototyping rooms?  I've done some
experiments with using a basic description based on sector_type for rooms
which have no description (none allocated) and ended up saving enough mem
to boost my test mud up to a little over 10k rooms, using only 4 and a half
megs of ram... some interesting possibilities for people doing up monsterous
grid-format or cube-format worlds...
