Comment(by pramsey):

 It might be hard to find the exact differences because this is going to be
 a difference between the tree distance and the edge distance algorithms,
 and the tree distance gets turned on as caching goes active. Replace
 testing ST_Dwithin with testing for differences between
 _ST_DistanceUnCached and _ST_DistanceTree to avoid cache effects.
