MegaPOV .5

It appears that if you #declare a pigment, and then try to put it into
the eval_pigment block, POV-Ray will force you to quit, due to an error.
This will cause POV-Ray to have an error:

#declare Pgmnt=pigment{ granite scale 10 }
#declare VectSample = eval_pigment( Pgmnt, <0,0,0> );

But this works:

#declare Pgmnt=pigment{ granite scale 10 color_map{[0 rgb 0][1 rgb 1]}}
#declare VectSample = eval_pigment( Pgmnt, <0,0,0> );

It appears you have to add a color_map to the #declared pigment to avoid
problems. I believe this to be a problem on the Macintosh version of
MegaPOV as well, since I was having problems earlier with it, but I
didn't know what was causing the errors.

I can confirm this bug. It causes a segmentation fault in this Solaris
compile of MegaPov.

Don't quite understand how it makes you quit POV-Ray (MegaPOV). Perhaps
this is true for other platforms but the mac version simply gives an
error and lets you continue to work.

This is indeed a bug and is fixed now for the next release.
