 It doesn't look like any replies to your message have appeared on the
 newsgroup.

 I have updated the povray port to version 3.7.0.8 but on High Sierra it is
 still giving me a similar error:

 {{{
 Persistence of Vision(tm) Ray Tracer Version 3.7.0.8.unofficial (clang++
 4.2.1 @
  x86_64-apple-darwin17)
 This is an unofficial version compiled by:
  MacPorts <https://www.macports.org/>
  The POV-Ray Team is not responsible for supporting this version.
 [snip]
 Assertion failed: ((pts >= PRETRACE_FIRST) && (pts <= PRETRACE_MAX)),
 function BeforeTile, file backend/lighting/radiosity.cpp, line 324.
 Abort trap: 6
 }}}

 Since I don't know anything about povray, other than what it is and how to
 build it, I would have to refer you back to the developers of povray for
 assistance in resolving this problem. Assertion failures usually indicate
 that there is a bug in the code, and only they know how to fix their code.
