#1767: Another bogus result from ST_Snap
 Reporter:  strk     |       Owner:  pramsey      
     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.1
Component:  postgis  |     Version:  2.0.x        
 Keywords:           |  

Comment(by strk):


 I think I get it: first the bottom-left corner of A (top-right triangle in
 the picture, with red vertices) gets snapped to top-left corner of B
 (bottom green triangle in the picture), then the bottom-right corner of A
 gets snapped to the top-right corner of B. In this case both distances are
 minor than 0.25.

 To be verified.
