IICRC... Rings a bell.

With yuqk, I do remember changing the code which creates the 0-1 ramp 
wave - in official POV-Ray there is some hard coded magic which 
sometimes causes trouble if one hits the right (wrong) values.

There is too some hard code clamping of values coming from functions 
into the pattern mechanism that I removed. However, this bit, from your 
results, I would say you are already avoiding. (That you are limiting 
your function() values into the pattern mechanism to 0-1 or >0.0 ranges)
