#1625: ST_Within and ST_DWithin disagree
---------------------+------------------------------------------------------
 Reporter:  strk     |       Owner:  pramsey      
     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.0
Component:  postgis  |     Version:  trunk        
 Keywords:           |  
---------------------+------------------------------------------------------

Comment(by strk):

 I suspect ST_Distance itself is kind of bogus.
 lw_dist2d_pt_seg in particular seems to be ending with projecting the
 point on the segment and then computing the distance ?
