Stack frame checking

Question

I have a 64bit visual c++ project. I create a new thread. It runs correctly if I have RTCs enabled.(Run time checking for stack frames).  It still runs when I have RTCs disabled, but the results are different. Is there some sort of memory setting I can change or something?

Provide a short concrete program that demonstrates the problem. Stating "results are different" is hopelessly bereft of information.

Incidentally, this post is best asked in the  C++ forum.

Answer 2

Here is the basic code that I create the thread in:

#include <thread>

static void task1()

{

do stuff

}

//code that starts the thread

{

std::thread t1(task1);

t1.detach();

}

note*

I read somewhere that threads were given 1 megabyte stack size.  I know I use more than that.  How do I change the stack size for this thread?

Have a look at this thread:

http://stackoverflow.com/questions/13871763/how-to-set-the-stacksize-with-c11-stdthread

... but perhaps you should re-design your code so that you don't need
such a large stack.

Hi John，

Since your question is about C++. I moved your thread to C++ forum for better support.

Thanks for your understanding.

Thank you.  Does anybody know about boost?  Is it up to date?  Their thread process allows for setting the stack size.

The _beginthreadex function allows for setting the size of the stack.  See https://msdn.microsoft.com/en-us/library/kdzttdcb.aspx

Answer 7

Ok.  I figured out what the problem was.  I didn't initialize a variable in a struct. The variable must have been a certain value when I used the RTCs option.  So the value was different when I disabled RTCs.  Thanks to all for the input.
