#342: Prepared MultiPolygon predicates leak memory
 Reporter:  olt         |       Owner:  geos-devel at lists.osgeo.org                    
     Type:  defect      |      Status:  new                                           
 Priority:  major       |   Milestone:                                                
Component:  Default     |     Version:  svn-trunk                                     
 Severity:  Unassigned  |    Keywords:  memory leak, prepared geometries, multipolygon
 Using prepared binary predicates like 'contains' with MultiPolygons leaks
 I have tested it with 3.1.1, 3.2.0 (using Shapely, which uses the C API)
 and latest trunk (r2982) with the attached C test program. So it might be
 a C API only bug.

 The test program does not leak if the predicate is called directly with
 the MultiPolygon (no prepared geometry) or if the prepared geometry is
 only a polygon.
