problem with MFC Diagnostics

So I gave up implementing my own memoryleak tracking (in this question overloading new and delete ) and try to use the MFC functions to identify my memory leaks. So I do exactly what's described here:

http://msdn.microsoft.com/en-us/library/8ky2wh64(VS.80).aspx

this is my code:

#ifdef _DEBUG
    CMemoryState oldMemState, newMemState, diffMemState;
    oldMemState.Checkpoint();
#endif

    int* test = new int;

#ifdef _DEBUG
    newMemState.Checkpoint();
    if( diffMemState.Difference( oldMemState, newMemState ) )
    {
        TRACE( "Memory leaked!\n" );
        diffMemState.DumpStatistics();
        diffMemState.DumpAllObjectsSince();
    }
#endif

but instead of outputting any useful information, the output shows

    Memory leaked!
        0 bytes in 0 Free Blocks.
        4 bytes in 1 Normal Blocks.
        0 bytes in 0 CRT Blocks.

......... and this is going and going and going and the number in th开发者_运维技巧e brackets is counting down (i actually never was patient enough to wait to let it count down to 1)

it's always starting at this high number 714538 so - what I am doing wrong?

Thank you!

From here it shows that DumpAllObjectsSince() should be called on the CMemoryState object you called Checkpoint() on.

So your code should be:

    {
            TRACE( "Memory leaked!\n" );
            diffMemState.DumpStatistics();
            //diffMemState.DumpAllObjectsSince();
            oldMemState.DumpAllObjectsSince();
    }
