Switch off Memory Leak Detection in boost.Test - c++

Question

I'm currently using boost.Test and I'm wondering if it might be possible to switch off the Memory Leak Detection, if one compiles in DEBUG Mode.
I don't want to use the command line parameter switch --detect_memory_leak=0. I'm looking for a kind of #define parameter, that switches off the memory leak detection feature in DEBUG mode.
It would be also suitable for me to switch off the memory detection feature by defining a certain compiler switch. I'm currently using Microsoft Visual Studio 2010.
#define BOOST_TEST_DETECT_MEMORY_LEAK 0 // Preprocesser switch I'm looking for!
#define BOOST_TEST_MODULE MyUnitTest
#include <boost/test/included/unit_test.hpp>
BOOST_AUTO_TEST_SUITE(MySuite);
BOOST_AUTO_TEST_CASE(MyUnitTest) {
/// Following code has a memory leak
/// ....
}
BOOST_AUTO_TEST_SUITE_END()

Answer 1

Just found out that possibly the best way to turn off the detection of memory leaks is to include the following code snippet into one's tests.
#include <boost/test/debug.hpp>
struct GlobalFixture {
GlobalFixture() {
boost::debug::detect_memory_leaks(false);
}
~GlobalFixture() { }
};
BOOST_GLOBAL_FIXTURE(GlobalFixture);
Still, I was not able to switch off and to switch on the detection of memory leaks for single tests.

You can directly set the environment variable BOOST_TEST_DETECT_MEMORY_LEAK to 0 or use putenv :
#include <cstdlib>
//...
BOOST_AUTO_TEST_CASE(MyUnitTest) {
putenv("BOOST_TEST_DETECT_MEMORY_LEAK=0");
//...
}
Edit
As you're using visual studio 2010, you can try _putenv or _wputenv :
#include <stdlib.h>
//...
BOOST_AUTO_TEST_CASE(MyUnitTest) {
_putenv("BOOST_TEST_DETECT_MEMORY_LEAK=0");
//...
}
Otherwise, I found a function detect_memory_leaks in the Boost documentation but it seems to be only available on recent boost version.

_CrtSetDbgFlag(0);
is the only thing that mostly worked for me. Leak messages came out, but not enough to make me wait.
Here's some code detailing everything I tried:
struct GlobalFixture
{
GlobalFixture()
{
// This doesn't seem to do anything
// boost::debug::detect_memory_leaks(false);
// This either
//_putenv("BOOST_TEST_DETECT_MEMORY_LEAK=0");
// This total hack also does nothing
// using namespace boost::unit_test::runtime_config;
// const_cast<boost::runtime::arguments_store&>(argument_store()).set(btrt_detect_mem_leaks, 0);
// This gets rid of most of the messages
_CrtSetDbgFlag(0);
}
};

Why not use the _DEBUG macro ?
#ifdef _DEBUG
#define BOOST_TEST_DETECT_MEMORY_LEAK 0
#endif
