  a parse error in Blockwall.inc

I don't know if we should discuss problems encountered with the use of 
objects from the Object Collection here.

Let me just put forward my puzzlement. When using the spline macro for a 
circular wall, I find that the diameter value often gives a parse error. For 
instance here, with 3.6*z:

#declare Blockwall_Spline =
spline {
  cubic_spline
  #local I = -0.25;
  #while (I<=1.25)
    I, vrotate(3.6*z,-y*I*360)
    #local I = I + 0.01;
  #end
}

The message says: "Attempt to access unitialized array element", and refers 
to line 1185 of blockwall.inc.

A value of 2.9*z for instance works correctly, but again, 5*z or 6*z lead to 
the same error. It seems rather random and I fail to see what goes wrong, or 
what I am doing wrong for that matter...

Any idea?

Thomas
