1773	Overlay operations kill the backend when passed input with NaN values  [FIXED BY GEOS-3.3.4]	strk	pramsey	"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.
