[geos-devel] Failures in testLeaksBig.xml

[Martin Davis]

I checked out the 5 failures in the testLeaksBig.xml file.  They're all
spurious, and due to the fact that JTS 1.4 now allows repeated points in
geometries, as per the SFS spec.

So these don't indicate any problem with GEOS.  You should fix up your
testLeaksBig.xml file to change the results of those cases to "true".
