OK

So I have downloaded and set up version 6.5.3 on a test system.  I then
altered the code on the example so that it no longer uses the PgEnv class.
I set my environment variable and ran the program now as below.  I still get
a huge memory leak.

Can I ask you what version you are using?

callproc(){
   PgDatabase* loStatsdb;

   loStatsdb = new PgDatabase("");
   delete loStatsdb;
};

main(){
    while(1){
        callproc();
    };
};
