----------------------+-----------------------------------------------------
 Reporter:  strk      |       Owner:  pramsey      
     Type:  defect    |      Status:  new          
 Priority:  critical  |   Milestone:  PostGIS 2.0.1
Component:  postgis   |     Version:  2.0.x        
 Keywords:            |

 ST_UnaryUnion doesn't survive NaN values:

 {{{
 strk=# select ST_UnaryUnion(
 '010200000002000000000000000000F8FF000000000000F8FF0000000000000000000000000000F03F'
 );
 The connection to the server was lost. Attempting reset: Failed.

 }}}

 The geometry is  LINESTRING(-nan -nan,0 1), created by a bogus ST_Split
 (#1772). Origin of this bug is #1771.

 Note that this is a GEOS bug so will need to be fixed there.
