Comment (by mdavis):

 Ironically, this bug is due to the high-precision evaluation of the line-
 point orientation predicate in GEOS.

 Not sure what a suitable fix is at the moment. Likely it will involve some
 sort of precision rounding, but that needs to be done carefully to ensure
 there are no other impacts.
