Bug: Wearing an item with only a hold flag will crash the game
Danger: Medium - Immediate crash, but only under select circumstances
Discovered in: AFKMud 1.77
Found by: Kazro
Fixed by: Samson

act_obj.c, wear_obj

Locate:
         if( IS_OBJ_FLAG( tmpobj, ITEM_TWOHAND ) )
         {
            send_to_char( "You cannot hold something while wielding a two-handed weapon!\n\r", ch );
            return;
         }


Change to:
         if( tmpobj && IS_OBJ_FLAG( tmpobj, ITEM_TWOHAND ) )
         {
            send_to_char( "You cannot hold something while wielding a two-handed weapon!\r\n", ch );
            return;
         }


A classic oversight of not checking to make sure that a previous return value wasn't NULL before checking the attributes on it.
