Fault tolerant heap on Windows 7

[FinderCheng]

Hi! I have recompiled my code on Windows 7 which woks well on Windows XP. When I run the exe file, there is a system error message:

FTH: (4544): *** Fault tolerant heap shim applied to current process. This is usually due to previous crashes. ***

But my application seems works well and nothing wrong happens.

I found this URL, http://msdn.microsoft.com/en-us/library/dd744764(VS.85).aspx.
It says that "in some cases, developers needs override the default behavior of this system",
but how? And in what cases? Now I don't know how to solve this problem or is it just OK?

Thanks!

Look in your code for: buffer overflow, double deletion or using a pointer that was deleted.

"Fault tolerant heap" basically means that you have some heap corruption, and windows will try not to crash your application (but i wouldn't rely on it to keep my application running or my data not corrupted)

Thanks, I'll check my code.

Typically, once your applications stop doing things that would normally cause it to crash (like double deleting), the FTH will gradually disappear.
