[postgis-devel] Possible Bug in isvalid()

[Markus Schaber]

Hi,

I just tried to apply my isvalid constraint to our raw data tables, and
got the following error message on one of them:

NOTICE:  AssertionFailedException: Unable to find a hole point not a
vertex of the shell
ERROR:  GEOS isvalid() threw an error!

This sounds rather strange to me. IMHO, it should not be possible to
make isvalid() throw an error by feeding it an invalid geometry.

I'll try to track down which geometries cause this error message...
