I have been using mlPov for some time with Terragen generated HDR images 
(either mapped on a cube or assembled with Sean O' Malley's cube2cross 
program  http://www.cs.uh.edu/~somalley/). It always crashes when the HDR 
image (lightprobe) is wider than it is tall with map_type 7 for a sphere. 
No problem with map_type 1, which works with latitude/longitude 
projections. This is minor and easily fixed.
The one I have a problem with, is that it seems to be crashing with an 
access violation, when the image is large. With a 4 Mb HDR image, it works. 
With a 12 Mb or larger one, it crashes. I haven't yet found the exact size 
where this happens. The 4 Mb image is the one that comes from 400X400 px 
cube frames and the 14 Mb one from 800X800 ones. And I was hoping to be 
able to use even larger ones! The small frames show a pixelated background 
in wallpaper size renders.
It is not a memory problem, since I have 512 Mb and the program rarely uses 
more than 150, even in complicated scenes. My system is Windows NT.
Is this a known problem? Is there something that can be done?
Help? Ideas? Suggestions?

Helen
