Comment (by mhugent):

 Ok, I compiled geos 2.2.3 and I also have the crash.
 The geos documentation also gives the reason (see below). I'm going to
 look for a workaround for geos2 (or an ifdef).

 /* May be called on all geometries in GEOS 3.x, returns -1 on error and 1
 00374  * for non-multi geometries. Older GEOS versions only accept
 00375  * GeometryCollections or Multi* geometries here, and are likely to
 crash
 00376  * when feeded simple geometries, so beware if you need
 compatibility with
 00377  * old GEOS versions.
 00378  */
 00379 extern int GEOS_DLL GEOSGetNumGeometries(const GEOSGeometry* g1);
