If you use pfSegsIsectNode(), instead of the compatibility
routine pfuSegsIsectNode(), you shouldn't have this problem.
You'll also get better performance.

If you must use pfuSegsIsectNode, recompile libpfutil.
There's a bug in libpfutil/isect.c. Line 114 should read:

retVal = PFTRAV_CONT|PFTRAV_IS_CLIP_END;

instead of

retVal = PFTRAV_CONT;

  Subject: Front Face Intersections

  When I ported and aplication from 1.1 to 1.2, the front-face
  intersection testing apears to have stopped working (most of the time).
  I am for now, using the pfuSegsIsectNode() function with plans
  to switch after the program is fully working. The aplication is
  running on a RE2. If any one has any sugestions, it would be
  greatly apreciated. -rb
