We're getting ready to port our mud to a new server and we're having a bit

account login and when we select what character to play the mud crashes.

These will give us the proper feedback on exactly what is causing the
crash. I'm willing to bet ch->usrdata is 0x0, or is 0x3 or some such
invalid mem address (caused by an overrun of some sort). If it is, you
may want to insert an alloc_mem in the new_char_data() and the
corresponding free_mem() in the free_char_data().

It's crashing while trying to update the listing of hosts that a players has
connected from.
/* consolidate list and remove the current host from the list, if needed
*/
might want to put this block inside a if ( ch->usrdata != null ) check
for ( h = 0; h < MAX_HOSTS; h++ )
{
if ( !str_cmp( ch->usrdata->alt_hosts[h], d->host ) )
continue;
if ( !IS_NULLSTR(ch->usrdata->alt_hosts[h]) )
{
hosts[i++] = str_dup(ch->usrdata->alt_hosts[h]);
free_string(ch->usrdata->alt_hosts[h]);
ch->usrdata->alt_hosts[h] = &str_empty[0];
}
}
The new server is running GCC 4.1.1 and any help would be greatly
appreciated. Thanks!
