for memory leaks
blackbiscuit
In MSVC, there is some function called _CrtDumpMemoryLeaks which helps
us to find the memory leak point in the source code. But may I ask if
I were programming on Linux platform or Mac OS X, is there any similar
way to detect the memory leak in the C++ source code? Is there any
such like functions in the standard library?
Thanks for your attention.
Best wishes,
Tony

For Linux, Valgrind is great! But the last time I used it, it did only
heap checks, not stack. There are commercial tools such as Rational
Purify that can check both heap and stack, but Valgrind is free and it
is a really useful tool. I know it works well for C, but I am not sure
if it is as useful for C++.

This is called "memory debugger" or "leak detector". There are hundreds of
them, just search the web.

No.

try valgrind - its a not a pinpoint app for memory leak, but a
comprehensive solution for memory issues, it is free and no recompile/
link is required, the penalty is in run time and used memory.

For big systems(say 0.5 million lines of code or more) Valgrind can
unfortunately severely impact on the
performance - even up to the point where it is basically not possible
to run the system.
On these occasions I've used LeakTracer or a modified version of it.
LeakTracer has minimal impact on performance.
It's a little bit limited but have caught leaks that were found by
Valgrind
Good luck (and here's the link: http://www.andreasen.org/LeakTracer/)

I have written a free memory debugger that may be of interest to you.
It is described in this page:
http://wyw.dcweb.cn/leakage.htm
One good thing about it is that you can use new(std::nothrow). Older
versions do not support it. It is also very efficient.
You can download it here:
http://sourceforge.net/projects/nvwa/files/

Yongwei

It is still very useful to check memory leaks when running unit tests.

You can partially check the stack (if using g++) with
"-fstack-protector-all". It adds some stack checking to functions.
