Hello,
I toiced in menay scenes that using radiosity often leads o crash of 
PovRAY. Am I the only one here with some problems ?
For every scene using radiosity - it either render succesfully, or crash 
just after end of rendering (probalby deallocation).
Crash means :
  - MsgBox iforming about problems, and suggesting to restart PovRAY
  - after closing box sometimes pov is working fine, sometimes it starts to 
print messages in [probably] endless loop :

  objects.cpp line 887
  NULL object removed 

and almost always print (instead Win98 report - PovRAY has performed 
illegal operaiton ...) :
  Returned from renderer due to access violation exception

I tested about 5 radiosity scenes (including 1 from include menu) and all 
have problems. About 1 of 10..20 renders crashes.

I have Athlon 1,7 256 RAM Win98 SE

Maybe I can run this radiosity scene in some debug mode ?

Well, you don't see this group full of such reports, do you?  ;-)

No, seriously, it is really hard to tell without a scene, but could it be
that you are testing with some glass objects, low adc_bailout, high
radiosity recursion level, or something similar?  If so try to increase the
max_intersections global setting.

Or did you overclock your system and/or memory?  Or do you have an unuaual
amount of memory banks in use, i.e. all banks with double-sided DIMM modules
(that is with chips on both sides of the modules)?  Do you have occasional
8every day or two) crashes with other programs as well?  In that case, clock
your system to a normal rate, make sure the RAM settings are conservative,
and if you have all banks full, remove one module.

Usually my English is bad but this time I don't undesrtand so much.

If I understand first sentence that you have crash on every radiosity scene I
can't notice anything like this on my system.

Since POV suggested you to exit it can be responsible for further behaviour.

IIRC some days ago somebody suggested to you it can be hardware problem. Have
you checked this ? Is your system overclocked or something ?

I have a Pentium II 233 128 RAM NT4

Sure. Just recompile POV in debug mode and use debugger.

  Can I add "check the CPU temperature"? And I speak here as experienced 
cpu-burner... :(
