First, I'm not familear with isosurface stuff (I haven't done any work on it
myself... well, except for preliminary work on UV mapping which has since
been scrapped).

Using the following for the isosurface function fixes the 'not enough
argumens' problem:
     function {FUNC1(x,y+cos(TH(x,y,z)*7)*0.3,z)}

Somebody apparantly changed the implementation of isosurfaces while we
weren't looking and those default parameters aren't there anymore.  maybe
that's the problem?

About that crash... I got it to crash once... but that happened before I
replaced the #declare TH=...

But can't get it to crash again now that I'm running the debugger.
Strange...

I haven't either. Right now I am simply rendering thumbnails of all of
the demos to help you track down bugs and to get a feel for what the
patch has to offer. I have been avoiding this for too long and it's
time I start to get up to speed on some of these new features.

With a little patience I was able to get it to stop crashing long enough
to return the following error message:

#declare TH= 
function{"FUNC1"}

isosurface {
     function {FUNC1(x,y+cos(TH <----ERROR

torus2.pov:16: error: cannot load function.

Returned from renderer (non-zero return value)

 Obviously it is a user created problem but the program seems a little
too sensitive to it.

If you haven't noticed, the demos for my features are usually somewhat
lacking.  If anyone wants to make up some demos for me to include, I'd be
happy.  :-)

I've had it crash under two situations:
1) an error causes parsing to stop
2) the scene finishes rendering and I see a bunch of 'tried to free NULL
pointer' errors and then it crashes

Don't worry.  It wasn't you.
