POV 3.5 RC6 icl on WinNT Sp 6 PII 233 with 128 MB

Following code together with +FN +KFF10 caused crash. When after restart of
POV I replaced clock with 0 and removed +KFF10 from settings then image was
rendered fine. This is a little modified source posted two posts earlier by
Richard.

global_settings { assumed_gamma 1.1 }
#include "stdinc.inc"
  background { color Blue }
  camera {
    location <0, 2, -10>
    look_at  <0, 0,  0>
  }
light_source { <0, 2, -10> colour White }
  sphere_sweep {
    //linear_spline
    //b_spline
    cubic_spline
    9,
    <0, 10, 0>, clock
    <0, 10, 0>, clock

    tolerance 0.000001 //0.2
     pigment { color Yellow }

Confirmed with W2k/PIII-1000/512Mb
 and both 3.5.beta.RC6.icl.win32 and
 3.5.beta.RC6.msvc.win32

The code below causes an error message:
"The POV-Ray core rendering code caused an access violation exception"
with empty command line and "640x480 AA",
but is happy with e.g. "320x200, No AA"
