Rashad,

The problem is that OLGeometry is an unitialized pointer as opposed to
being a valid geometry object on which a method could be invoked.

I would suggest changing this to:

   OGRGeometry *OLGeometry = NULL;
   char *geom = "POINT(6 10)";

   OGRGeometryFactory::createFromWkt( &geom, NULL, &OLGeometry );

Note that the documentation on OGRGeometry::importFromWkt() says:

  * The object must have already been instantiated as the correct derived
  * type of geometry object to match the text type.  This method is used
  * by the OGRGeometryFactory class, but not normally called by application
  * code.

Best regards,
