OCCI ResultSet problems

Question

Hi!
My problem is the same as this thread.
OCCI programming
I call the method getColumnListMetaData and the method returns a STL vector with
Metadata objects and it works fine. My problem is when the vector should be deallocated.
When I run the testprogram a get this error message:
*** glibc detected *** double free or corruption (!prev): 0x08121568 ***
The sample code....
vector<MetaData> md = rs->getColumnListMetaData();
//column names to number mapping
map<string, int> columns;
for (int i = 0; i < md.size(); i++)
     columns[md[ i ].getString(MetaData::ATTR_NAME)] = i;
My versions:
CentOS release 4.2 (Final)
Kernel 2.6.9-34.EL
gcc version 3.4.4
OCCI 10g Release 2 (10.2)

Code:
int test(int argc, char **argv)
     const string userName = ".........";
     const string password = "....";
     const string connectString = "..";
     Environment *env = Environment::createEnvironment();
          Connection *conn = env->createConnection(
               userName, password, connectString);
          Statement *stmt = conn->createStatement(
               "SELECT * FROM TEST_TABLE");
          ResultSet *rs = stmt->executeQuery();
          vector<MetaData> md = rs->getColumnListMetaData();
          //column names to number mapping
          map<string, int> columns;
          for (int i = 0; i < md.size(); i++)
               columns[md[ i ].getString(MetaData::ATTR_NAME)] = i;
cout << "Column name: " << md[0].getString(MetaData::ATTR_NAME) << endl;
          stmt->closeResultSet(rs);
          conn->terminateStatement(stmt);
          env->terminateConnection(conn);
Environment::terminateEnvironment(env);
return 0;
Output:
Column name: ID
