I don't think the address particularly matters, unless you did a gdb -c 
core and it gave you the variable or function name where it happened.

Well, you might.  More likely you're just trying to access memory your 
process does not have sufficient access rights to.  Should be a 
segmentation fault (or SIGSEGV) that it's giving you, that seems to be 
the standard UNIX catch-all i80386 exception signal.

Possibly your MUD has run out of memory.  Not the computer, necessarily, 
but the MUD process;  I'm not sure how Circle handles this, but I know 
that certain other DikuMUD-derived MUDs use a static maximum amount of 
memory that usually allows for only an expansion of about 20% before you 
run into memory problems.  Maybe someone else can enlighten us both on this?
