Hehe, It's a problem you're unavare off unless you accidentially stumble
across it. The problem is, that you're most probably exceeding the
buffersize of the buffer you're using. I calculated the buf to be able to
take 4 pages of 'full screen info' without colors, less with, and some
more if you don't use all 80*24 chars ona screen.

You need to go into do_show and make a NEW buffer let's say... buff (two
f's :) thats bigger, like char buff[32000];  or to make sure you don't
exceed the size of buf when showing zones..
you could do it using this kind of check:

  if (strlen(buf) + 50 > sizeof(buf))

The 50 I add to the strlen is what I recon a line will use, you might want
to change it to 100 if the mud still crashes. If the IF statement is
'evaluated as beeing true' you have a problem. This means you're close to
exceeding the size of buf. Invent some way of handling the error :)
