Memory Leak in OCCI library

Question

Hi,
I am using OCCI library and oracle XE. There is noticeable amount memory leak in CreateEnvironment and CreateConneaction API funtions. I am not sure whether it is known problem. If the oracle server is down my application has to retry several times using these above mentioned methods and memory grows significantly.
Here is a simple program which creates environment and create connection and terminates immediately in a while loop. We see huge memory leak.
I have downloaded occi_gcc343,
Here is sample program which i tried.
#include <iostream>
#include <occi.h>
using namespace oracle::occi;
using namespace std;
int main(int argc, char* argv[])
Environment *env = NULL;
Connection *conn = NULL;
while(1)
Environment *env  = Environment::createEnvironment(Environment::DEFAULT);
Connection *conn = env->createConnection ("cvo","cvo123","XE");
sleep(3);
env->terminateConnection (conn);
Environment::terminateEnvironment(env);
getchar();
return 0;
Please let me know if there is any patch available or is there anyway overcome from this problem.
Thanks,

Can't really speak about the memory leak issue that you suspect with the library, but do note that that you do not need to terminate the environment in a reconnect loop. terminateEnvironment is meant to be called at program exit, not disconnect. This may help with the memory issue somewhat.
