[postgis-users] Intersection errors out with null directed edge

[Chris Hermansen]

Hi folks;

I had this problem today:

AssertionFailedException: EdgeRing::computePoints: found null Directed
Edge

I see in the archives that there are others who have suffered this, back
in 2006 and then in 2005, but there don't seem to be any offerings of
techniques to either repair the code or the data - and based on the
error above, I'm not sure which is ultimately at fault.

Does anyone have some more up-to-date thought on this?

I'm running postgis-1.3.1 on Ubuntu with the packaged postgresql-8.2
installed.

Thanks in advance!
