 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?
