Comment #1 on issue 86 by mark.cav... at siriusit.co.uk: ST_LineToCurve  
produces invalid curves

I think the key to this is that the generated CURVEPOLYGON is actually  
invalid. When
trying to parse the geometry using SVN trunk, I get a "parse error - invalid
geometry" message which points to a parse failure at character 104 which  
looks like this:

-2.51624134379182e+307,nan ...

Hmmm. So it looks like the parser (possibly correctly) is choking on the  
NaN. My
guess would be the CIRCULARSTRING generation code should not output this  
value rather
than the parser being altered to accept it?
