Crash using Timestamps

Question

Hi,
I have (at last!) a simple program that accesses a simple DB. I have one table that contains a column of type TIMESTAMP.
I want to use this timestamp eventually to select a range of data (perhaps using between or something like that). But to test my program I have first just a simple query to select the timestamp field:
Stmt->setSQL("SELECT dzupd FROM erec_t");
Works fine. However I now want to select data with a particular timestamp. So I am trying:
Timestamp tsStart;
tsStart.fromText ("01/04/06 00:00:00", "DD/MM/YY HH24:MI:SS", "" , env);
Now, without doing anything else with the timestamp, the program runs as before, outputs all the data, and then crashes. The information I have seems to indicate a problem with the oraclient10.dll:
AppName: oracle2.exe     AppVer: 0.0.0.0     ModName: oraclient10.dll
ModVer: 10.2.0.1     Offset: 000ad0f7
I am using Oracle 10g on Windows XP.
Any advice would be much appreciated.
Many thanks.

Thanks for the tip.
I will need to study the link properly, but creating the environment is first thing I do and terminating it is the last.
The code is very simple and looks like this:
// Oracle2.cpp : Defines the entry point for the console application.
#include "stdafx.h"
using namespace oracle::occi;
using namespace std;
int tmain(int argc, TCHAR* argv[])
//create environment and connection
Environment* env = Environment::createEnvironment();
cout << "Environment created" << endl;
Connection* conn=env->createConnection("tester","tdb","testdb");
//3rd parameter is db name/TNS alias
cout << "Connection made" << endl;
// build SELECT statement
Statement* Stmt = conn->createStatement();
Stmt->setSQL("SELECT dzupd FROM erec_t");
Timestamp tsStart;
tsStart.fromText("01/04/06 00:00:00", "DD/MM/YY HH24:MI:SS", "" , env);
ResultSet *rs = Stmt->executeQuery();
while (rs->next())
     Timestamp st = rs->getTimestamp(1);
     cout << "\t\t" << st.toText("dd/mm/yyyy hh:mi:ss",1) << endl;
Stmt->closeResultSet(rs);//to free resources
conn->terminateStatement(Stmt);
//logoff and terminate connection
env->terminateConnection(conn);
cout << "Connection terminated" << endl;
//terminate Environment by calling static method
// Environment::terminateEnvironment(env);
cout << "Environment terminated" << endl;
     return 0;
I think it is all done within the correct scope but I will study it more closely.
Thanks for the tip.
