Greetings,
I was just playing around with subsurface, and got a crash:
povray: render/trace.cpp:3452: void
pov::Trace::ComputeOneSingleScatteringContribution(const
pov::LightSource &, const pov::Intersection &, double, double, double,
pov_base::GenericRGBColour<float> &, double, const pov::Vector3d &,
double, double, pov::Trace::TraceTicket &): Assertion `(factor >= 0.0)
&& (factor <= 1.7976931348623157e+308)' failed.
It's a bit lock with the compiler:
* if I use the gcc compiled povray, it survives and render the attached
png.
* if I use the icpc compiled povray, it crash.
It seems the crash appears when the cyan pixel get computed.
Any clue about subsurface ? Did I forget something ?
(And yes, the picture is ugly, but it's mine and sort of minimal :)

I should read the big Warning in the wiki!
Shame on me.

I don't know, but my render looks a bit different. The cyan border is much
thicker, and surrounds the entire object.

Speaking of documentation, it also says not to use zero as a channel value. I
tried it with rgb <1,0.01,0.01>, and it looks much different. It also took
I've posted my results in p.b.i.

The warning is the last paragraph before the Highligts title
