htimage bug?

I am using the htimage pre-compiled binary for
RS6000, and it's throwing spurious results for
certain polygons. For example, when I define the
polygon:

poly (270,207) (266,207) (266,211) (265,211)
(259,212) (259,209) (254,210) (254,197) (257,197)
(257,181) (270,181) (270,207)
/cgi-bin/moutm05b.pl?BOLLINGER

htimage considers any point from (1,207) to
(270,207) "in" the polygon. (As well as the points
actually within the polygon).

I've tried reversing the polygon, rotating the
points, removing the duplicate endpoint - result is
still the same.

This polygon works fine when tested in mapedit.

Any help would be appreciated. Thanks.
