How turn off memory leak dumping?

My Vis C++ program takes forever to exit. Reason: it is dumping potential
memory leaks. I like finding leaks once a month, but not every time I run.
How do I turn mem leak dumping off?

I looked in help, and it said leak dumping is enabled with #define
CRTDBG_MAP_ALLO C ... but I do not have that #define anywhere in my code.

I _do_ have the /RTC1 (same as both /RTCs and /RTCu ) but the help for those
says nothing about memory leaks; and Id like to leave /RTC1 on all the time.

Thanks in advance for any help,
neal

In non-MFC applications, you can use _CrtSetDbgFlag function.
(Since the leaks are dumped, it is possible that this function is already used somewhere
in the application)

In MFC applications, you can use AfxEnableMemory Tracking function.

Hallo Oleg!

(Since the leaks are dumped, it is possible that this function is already used somewhere
in the application)

In MFC applications, you can use AfxEnableMemory Tracking function.


The MFC version finally calls _CrtSetDbgFlag too!

Yes, it does.

Calling AfxEnableMemory Tracking(FALSE) is just a bit simpler and less error prone
(e.g. because it is natural to use _CrtSetDbgFlag to clear _CRTDBG_LEAK_CH ECK_DF
flag and expect it to suppress the leak report, but in case of MFC it will not work.
Instead _CRTDBG_ALLOC_M EM_DF should be cleared, and that's what
AfxEnableMemory Tracking does)

Hi Guys, I've been try to use Dinkum STL library. It workes well first, but report memory leak in MFC Debug Mode. I use Dinkum Unabridged Library for VC++ V4.02, MSVC6, WIN2000 SERVER. I made a dialog based program by MSVC6, inserted simple code to use Dinkum STL Library, and added simple code like this.

Hi all, quick question. I have an application I'm running. There are some "fatal" error conditions that could occur during processing, and I want to exit immediately if one comes up. When I put an exit() function call in my code I get a message like this: Detected memory leaks! Dumping objects -> {177} normal block at 0x003864E8, 32 bytes long.
