Dear Colleagues,

     this is a question for povray programmers. I am experiencing an

increasing number of crashes of povray with the error message

"Floating exception" on DecAlpha machines running Linux or Digital Unix.

The scene and the image is very large and I assume that this is why I get

all the trouble: 250000 scene objects, 2400x2400 pixel -> 750 Mbyte.

It seems that it runs a bit better under Digital Unix than under Linux but

I wish someone would come up with a stable version of povray 3.0 because every

crash is extremely costly and it takes about 2 h for the parser to read

in the scene objects. Povray usually runs for about 1 - 2 h so I loose about

50 % cpu time pro crash.  To sort of explore the options and maybe even solve the

problem myself I tried to compile povray with any available c compiler (cc,gcc,c89)
and

a number of different optimization options ... but it was in vane.

Any ideas ? Is this a povray problem or a problem of the operating system ?

Any help is much appreciated.
