------------
When extracting the second object that is to be extracted since the game
booted, the game crashes. I've compared my extract_obj() and
REMOVE_FROM_LIST against stock code and they are identical, so the cause
of the crash has to be from somewhere outside these sections of code.
I have no clue as to what is causing this at all. It's as if items are not
being added to the object_list properly, or are being removed from the
object_list prior to extract_obj() being called. Following this idea, I
checked read_object() and found it identical to stock. I also grepped for
object_list and check all occurances. Everything there is stock for
adding/removing to/from the object_list.
I crashed my test port 14 times within the past hour to see if I can glean
the cause of the crash. From the looks of things it is crashing when
it hits the first or last item in object_list while extracting the
obj after extract_obj() has been called once before on that object.
Oh jeez... I hope this makes sense to someone out there because I am
totally missing the cause.
If someone could glean some light on this one, please help me out.
Thank you,
