Is obj->pIndexData->name null? I don't see what that would cause a crash, though you can check that QUICKLINKS checks for null input.

Not sure.

(gdb) p obj->pIndexData->name
Cannot access memory at address 0x2c

Let me look over QUICKLINK


mud.h:#define QUICKLINK(point)  quick_link((point))
mud.h:#define QUICKLINK(point)  str_dup((point))

char *quick_link( char *str )
{
    register struct hashstr_data *ptr;

    ptr = (struct hashstr_data *) (str - sizeof(struct hashstr_data));
    if ( ptr->links == 0 )
    {
        fprintf(stderr, "quick_link: bad pointer\n" );
        return NULL;
    }
    if ( ptr->links < 65535 )
        ++ptr->links;
    return str;
}

This may be the problem:

(gdb) p *obj
$1 = {next = 0x0, prev = 0x0, next_content = 0x0, prev_content = 0x0, first_content = 0x0, last_content = 0x0,
  in_obj = 0x0, carried_by = 0x0, first_extradesc = 0x0, last_extradesc = 0x0, first_affect = 0x0, last_affect = 0x0,
  pIndexData = 0x0, in_room = 0x0, name = 0x0, short_descr = 0x0, description = 0x0, action_desc = 0x0, item_type = 0,
  mpscriptpos = 0, extra_flags = {bits = {0, 0, 0, 0}}, magic_flags = 0, wear_flags = 0, mpact = 0x0, mpactnum = 0,
  wear_loc = -1, weight = 1, cost = 0, level = 0, timer = 0, value = {0, 0, 0, 0, 0, 0}, count = 1, serial = 0,
  room_vnum = 0, ashards = 0,
  creator = 0x83a7770 "(null)\n\rVnum         1007\n\rLevel        115\n\rValues       10 10 0 0 0 0\n\rEnd\n\r\n\r#END\n\r"}

Well I've had it working for a while. But a quick question. Adding a new object string, I had to go through all this. Yet I've added two new object variables, and it's fine. Why is this?
