I heard that this was a only problem with the Windows version... are there
any UNIX (or other) people out there who can confirm/deny this rumor?

Perhaps you know the tool "purify". It checks the usage of memory and finds
almost every error. I've just used it with POV-Ray to render a scene that
uses more than 60 MB on a Sun Enterprise. There wasn't any memory leak - not
a single byte. The scene contains spheres, cylinders, bezier patches and a
plane. At least these features seem to work perfectly.
However, you may want to send me a scene that causes problems on a Windows
machine, and I will check it.

After replacing "finish{Fin}" by "finish{Dull}" it rendered flawlessly on a
Sun, and purify didn't report any errors. AFAIK the generic unix version
corresponds to 3.01.

No, I get these informations from the "About" dialog of POV-Ray for
Windows... I think there's no unofficial compile of version 3.1 by
now, because the sources aren't still available.
