pfSegsIsectNode should only invoke this function when
the mode contains PFTRAV_IS_BCYL, which your example
does not. Could something else be stomping on the mode
in the segset?
If you can reduce it to a simple test case, I'll look
into it. Otherwise, a stack trace using "-g" and the
debug Performer libraries (libpf-g.a/libpr-g.a) might
provide some clues as well.

The pfSegSet is not modified by the traversal.
It's an exposed struct, so what you set is what
you get. Typically, you'd be updating the position,
direction and length of the segments every frame.
