Ok, perhaps it is that the loader does a pointer == NULL test, but perhaps we
never initialize it to NULL, and it's just a coincidence that it works on my
system? I have to check it out...

Sounds plausible, but I haven't really looked at this part of the code, since
it seemed to work on my system - obviously I will have to look into it now.

No, I work under Linux (SuSE 6.3), and as mentioned before, I don't have any
trouble with this. Loading chevy.3ds produces a model of a car standing on a
large square. Some texture coordinates are missing though.

Thanks for the error report, I will have a look at it.
