[gdal-dev] forceToPoly causes crash when converting geom to json

[Ari Jolma]

No problems at least on the other side of bindings:

my $g = Geo::OGR::Geometry->new(
     WKT=>'MULTIPOLYGON(((1 1,5 1,5 5,1 5,1 1),(2 2, 3 2, 3 3, 2 3,2 
2)),((3 3,6 2,6 4,3 3)))');
my $h = $g->ForceToPolygon;

say $h->AsText;
say $h->As(Format=>'GeoJSON');

output:

POLYGON ((1 1,5 1,5 5,1 5,1 1),(2 2,3 2,3 3,2 3,2 2),(3 3,6 2,6 4,3 3))
{ "type": "Polygon", "coordinates": [ [ [ 1.0, 1.0 ], [ 5.0, 1.0 ], [ 
5.0, 5.0 ], [ 1.0, 5.0 ], [ 1.0, 1.0 ] ], [ [ 2.0, 2.0 ], [ 3.0, 2.0 ], 
[ 3.0, 3.0 ], [ 2.0, 3.0 ], [ 2.0, 2.0 ] ], [ [ 3.0, 3.0 ], [ 6.0, 2.0 
], [ 6.0, 4.0 ], [ 3.0, 3.0 ] ] ] }
