bug in os/x version of conserver

This might actually break on other versions, I don't know.

Given this snippet of (incorrect) config file:

default csrvcs5 {
type exec;
host aconsole.com;
# initcmd '/opt/test/etc/shiva-chat';
# exec /usr/bin/telnet -E H P;
execsubst H=hs,P=Pd;
portbase 3000;
portinc 1;
}

conserver crashes with a bus error

yikers. i took the chunk of config file and included it in a normal
config file, trying to include it in a console definition and not.
nothing bad happened. is there a full config file you can share that
tickles the problem?

btw, thanks for the OS X notes for compilation, etc you sent directly to
me. i'll work on integrating them to make it easier in the next
release.

thanks for sending the config file. yep...there's a bug. here's a fix
to get around it (might not be my final fix, but perhaps). figured
everyone might want it, just in case...

*** cutil.c.old Wed Oct 26 12:18:39 2005
--- cutil.c Wed Oct 26 12:17:23 2005
***************
*** 3187,3193 ****
OutOfMem();
}

! if (s != (SUBST *)0 && repl != (char **)0) {
static STRING *result = (STRING *)0;

if (result == (STRING *)0)
--- 3187,3193 ----
OutOfMem();
}

! if (s != (SUBST *)0 && repl != (char **)0 && *repl != (char *)0) {
static STRING *result = (STRING *)0;

if (result == (STRING *)0)
