The following short scene causes POV-Ray to give me an "internal error"
warning. I would imagine the problem is the exp() function, but surely a
simple high-valued result shouldn't crash the whole of POV-Ray... I would
have expected to just get some kind of "number overflow" message instead...

POV-Ray 3.5.icl.win32
Windows XP (Home), Mobile AMD Athlon +1400 CPU, 256MB RAM, etc.

Yep, crashes rather violently. I suggest you post it as a bug report in the
bug reports group and, if you like, you can mention that I confirmed it so
that the bug report moderator will accept it.
