I think that's the same bug that made the waveform sample in the insert
menu crash.  An '#undef Fn' between should help.

I'm not able to find that waveform sample.
Where is it ?

And where can I find the bug report for this ?

In the insert menu: Pattern-Texture Attributes/waveform attribute

In fact that bug already occurred in beta 5:

Hmmm...

Thorsten says that this bug is the same as one 


In that post he mentioned "POV3.5b2".
Subject: "number of parameters in functions"

Does this mean that your post, ABX's and mine is
all about the same bug ?

And that it appeared for the first time in beta 2 ?

Found it.

So it didn't crash because of the constant function,
but because of the redeclaration of the function ?

If so, then the "name" of the bug is a bit misleading,
isn't it ?

Yes, after some analysis this seems to be the case.

I'm the author of this post but I tested this bug with beta 6 and it
works fine on the same machine (but I had to add three args within
last line)

Seems to be.  If this is the case it's also the same bug that behaved
differently with the Intel/MSVC compile and on the different machines.
