I have the following C program:

#include <stdio.h>

int main() {
    int i = 0;
    int N = 10;
    while(i < N) {
        printf("counting to %d: %d", N, i);
        //i = i   1;
    }
    return 0;
}

I would like to compile this first to assembly, then to binary for instructional purposes. So, I issue the following commands:

$ gcc -S count.c -o count.s
$ as -o count.o count.s
$ ld -o count -e main -dynamic-linker /lib64/ld-linux-x86-64.so.2 /usr/lib/x86_64-linux-gnu/libc.so count.o -lc

These compile the C to assembly, assemble the assembly to binary, and then link the library containing the printf function, respectively.

This works. Output:

counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0counting to 10: 0

etc until I ctrl-c the program.

However, when I uncomment the i = i 1 line:

Segmentation fault (core dumped)

What is going wrong here?

UPDATE: Here is count.s (with the i = i 1 line included)

    .file   "count.c"
