You need to paste or link to div.c, otherwise this seems a pointless exercise.
See, I cannot repro:

$ cat div.c
#include <stdio.h>
int main() {
 puts("hello world");
}

$ x86_64-w64-mingw32-gcc -o div div.c
$ ./div
hello world

$ x86_64-w64-mingw32-gcc -fstack-protector-strong -o div div.c
$ ./div
hello world

$ ldd div
