作者使用VC6.0进行软件调试时遇到问题，希望通过宏__UHEAP_FAILNEXT(1)等手段故意触发内存溢出错误来检测内存泄漏。但无论是否将分配的内存放入CleanupStack中，模拟器总是显示相同的内存不足提示，无法确定是否存在内存泄漏。

I cannot solve this problem yet. I'm using VC6.0 as debug tool. I know I can produce deliberate out-of memory errors by macro __UHEAP_FAILNEXT(1), or User::LeaveNoMemory(). But How can I know whether memory leak occured after the fail? I've written the following code:

__UHEAP_MARK;
TInt32 *aaa = new(ELeave) TInt32[100];
//CleanupStack::PushL(aaa);
__UHEAP_FAILNEXT(1);
TInt32 *bbb = new(ELeave) TInt32[100000];
__UHEAP_MARKEND;
__UHEAP_MARKENDC(2);

and I found no matter I push aaa into CleanupStack or not, the emulator just displays the same information:"The memory is not enough, please close some applications and try again." -- That is, I still cannot tell out whether aaa has been orphaned in the memory.
I think, since such deliberate out-of memory producer tools have been designed, they must be designed to be used together with memory leak detecting tools, isn't it?
How do you do test? Thank you very much!
