problems with cstdlib + stdlib.h?

These errors are stumping me. There seems to be a problem with cstdlib and/or stdlib.h.

Has anyone seen these types of errors before

I am using Visual Studio 2005.

problems with cstdlib + stdlib.h?

Manesh_myworld
The solution involved removing this line
"_CRTDBG_MAP_ALLOC"

from the preproccesor definitions.

How it got there, I do not know, it was not in the make file for the project. If anyone has had a similar problem and knows why it occured, I would like to know why.

Here is something that might help anyone diagnose the problem.

The program compiles and runs in release mode, however these issues occur only when trying to compile in debug mode

You can actually diagnose the problem your self by using the /P compiler option which preprocess your code and produces a preprocessed version of your file. Compare the release with the debug and see what is the difference in definitions that leads to this error.

This is happening to me now. I don't even have those files included, and I am getting the error. It doesn't matter if it is Debug or Release for me, it just won't compile. So I tried the /P option, and it compiles, but it doesn't give me the file with the preproccessor code passed through it. Any advice

<edit>

Got it. I added #define _CSTDLIB_ before all my headers, and the error went away. I figured it wasn't reading the file correctly, that or out of order.
