About stack Overflow and manual open stack

Let's start with the question:

1. Why is there a stack overflow?

1. When recursive invocation, the depth of recursion will cause the system stack Overflow

2. When an array is defined directly in the function, the array space is too large, (the directly defined array in the function is the application space in the stack area, the stack space is limited
If it is defined outside the function, it is applied in the heap, so the large array needs to be defined outside the function)

2. How do I manually open the stack?

Microsoft's compilers (C + +)

#pragma COMMENT (linker, "/stack:102400000,102400000")

g++

    int size = << 20; 256MB    Char *p = (char*) malloc (size) + size;    __asm__ ("Movl%0,%%esp\n":: "R" (p));
