Description
I'm most likely doing something stupid. I'm trying to create a simple union between two polygons...
I'm using version 3.2
GEOSContextHandle_t handle = initGEOS_r( exception_handler, exception_handler);
GEOSGeometry * poly1 = GEOSGeometryFromWKT_r (handle, "POLYGON((0 1,0 8,1 8,1 1,0 1))");
GEOSGeometry * poly2 = GEOSGeometryFromWKT_r (handle, "POLYGON((0 0,0 1,8 1,8 0,0 0))");
GEOSGeometry * poly2 = GEOSUnion_r(handle,poly1,poly2);
I get "assertion failed: intSegs.size() == 4, file FastNodingValidator.cpp, line 60"
What am I doing wrong?

Nothing wrong I can think of. Try with current SVN version of GEOS, and also see if you can produce an XML based testcase (see tests/xmltester/tests/bug275.xml for an example)

FYI: using geos-svn here gives good result:
POLYGON((0 1,0 8,1 8,1 1,8 1,8 0,0 0,0 1))

Replying to PeteS:
NOTE: Just to clarify, there's a typo in the description, the final line of code should read "GEOSGeometry * poly3 = GEOSUnion_r..." not poly2
