Well...it took a while to track down my problem. I was, indeed, stuffing
NAN's into a pfSegSet segment.segs[].pos[] vector.

Two things I would like explained for my own info:

1) I was running with pfNotifyLevel(PFNFY_FATAL) but performer never
complained. Is this because it will only output messages if Performer
generates NANs, but will do nothing if it starts with bad info in the
first place.

2) When it happened, it seemed to "infect" all intersection tests --
even ones not related to the above problem -- so that they also
started to return bogus (i.e., NANs) results when fed proper
numbers. Is this behaviour to be expected?

Thanks to all who helped,
scott
