It does work when I #declare min2=function(x,y){select(x-y,x,y)}
and then replace min with min2.

So something concerning the min/max functions is broken.

I think it is related to Suzuki's isosurface bug, because when I replace 
min with & or | the behavior is the same, but if i replace it with a 
different function (for example sin(x*pi/2)*sin(z)*pi/2)) it works as 
expected.
