#2020: Regress windows 32 9.2
  Reporter:  robe     |       Owner:  pramsey

  Priority:  medium   |   Milestone:  PostGIS 2.1.0
 Component:  postgis  |     Version:  trunk        
Resolution:  fixed    |    Keywords:               

Comment(by robe):

 strk -- whatever it is, it only exhibits itself on windows PostgreSQL 9.2
 32-bit (none of the other windows variants I have show this, and no one
 else has the environment to trigger this).  So you being a windows hater
 shouldn't care :)

 Like I said -- it's something Paul changed in: r10335

 The question is a stupid one to begin with because ST_3DExtent gives bogus
 answers for the Z coordinate for any 2D geometry and even in 2.0.1 has.
 For example on my 64-bit 2.0.1 9.2 install I get

 SELECT ST_3DExtent(ST_Point(i,j))
 FROM generate_series(1,10) as i cross join generate_series(11,20) As j;

 BOX3D(1 11 0,10 20 1.24562170568925e-316)

 So when we then have the nerve to then mix 2ds with 3Ds and ask for the 3D
 extent of such a bastard, it is amazing that so many platforms agree.

 anyrate it's not something Paul has the time to debug and not one I want
 preventing me from regress testing my 9.2 32-bit.
