[Radiance-general] Segmentation fault

[Ignacio Munárriz]

Thanks greg, i'd prefer unix too, but all clients work with autocad...
I've calculated it with other computer and here are the results
http://www.aisarquitectura.com/todofinv3.jpg , each of those trees are 40mb
instances, radiance is amazing but it's a little hard working with colors
and textures in a text editor,
Ignacio

Hi Ignacio,

 From my experience, there are memory problems associated with
Cygwin, and these are unrelated to Radiance (other than the fact that
Radiance uses a lot of memory).  A backtrace isn't much help in this
case, I'm afraid, as it is not a problem with the program, but with
the system under which it is operating.
