c++ - How to end up with a pointer to 0xCCCCCCCC

Question

The program I'm working on crashes sometimes trying to read data at the address 0xCCCCCCCC. Google (and StackOverflow) being my friends I saw that it's the MSVC debug code for uninitialized stack variable. To understand where the problem can come from, I tried to reproduce this behavior: problem is I haven't been able to do it.

Question is: have you a code snippet showing how a pointer can end pointing to 0xCCCCCCCC?

Thanks.

Answer 1

int main()
{
    int* p;
}

If you build with the Visual C++ debug runtime, put a breakpoint in main(), and run, you will see that p has a value of 0xcccccccc.
