[geos-devel] CVS PrecisionModel segfault on Windows MSVC 7.1

[Charlie Savage]

There is nothing in the updated SWIG bindings that would affect Geometry 
factories or precision models.  However, there are changes with passing 
vectors of coordinates and geometries to functions.  Do you have some 
test code I could look at?  This could be caused by one of the methods 
your are calling taking over ownership of the geometry, but Python 
doesn't know it.
