Bleh, not so random. I did something to crash quite regularly. And it's 
happening in povconsole64.beta.4 too.  I will update and chase. :(

Another stack thingy?

I'm trying to do 700 quick frames. Most scene features are turned off so 
I can check timings and positions of a new colefax spline move.

It did 2 frames and then:

==============================================================
@@begin

F:0105  Camera= <488.99, 53.25, 151.06> Lookat= <485.90, 53.25, 162.65>
File '../haus/famroom.inc' line 179: Possible Parse Error: Unmatched {
File '../haus/famroom.inc' line 199: Parse Error: No matching }, camera
  identifier found instead
Fatal error in parser: Cannot parse input.
Render failed
==============================================================

So I start again at frame 105 and it does that one and dies on 106.
Lather, rinse, repeat.
Usually it silently fails. When it does say something, it is that odd 
camera in famroom. (Line 199 is a moderate macro that in this case is 
emitting a single tiny clear sphere at the origin to satisfy the 
enclosing union @ line 179.)

@@begin is the second line of code (after #version 3.7)
@@end is the last line of code

The spline preview looks ok...
