[geos-devel] Memory leaks (?) experienced with WKTReader and WKBWriter

[Manos Karpathiotakis]

Hi all!!

I am currently using geos 3.2.0 in an implementation of mine. The classes I
am mainly using are Geometry, WKTReader and WKBWriter.

However, after examining my code with valgrind, it seems that I am
experiencing memory leaks from the two WKT classes.
The block of code that contains those is the following:

WKTReader* reader;
WKBWriter* writer;
for (unsigned i = 1; i <= 1000000000; i++) {
                //
                //create the wkt geometry...
                //

                string wkt = sObj.str();
Geometry* geom = (*reader).read(wkt);
                (*writer).writeHEX(*geom,geo_values);
 //reader->~WKTReader();
//(*geom).~Geometry();
 //free(geom);
//delete reader;
}

The lines commented at the end of the block are my attempts to perform
garbage collection manually.
So, my question is the following: Is there a specific way to destroy the
Geometry/WKTReader/WKBWriter??
Is it possible to avoid the leaks I am experiencing?


Thanks a lot,
Manos
