#3448: ST_Distance yields inconsistent results when used in a statement involving
multiple Point and Multipolygon Geography pairs
----------------------+-------------------------------------------
Reporter: ewcz | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 2.2.3
Component: postgis | Version: 2.2.x
Resolution: | Keywords: ST_Distance, _ST_DistanceTree
----------------------+-------------------------------------------
Comment (by pramsey):
The point-in-polygon test is short-circuiting the calculation early with
an erroneous result, hence the zero distance return. Why? Dunno, probably
a robustness failure in the spherical geometry core algorithms, gah.
