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
ntdll.dll => /cygdrive/c/Windows/SYSTEM32/ntdll.dll (0x773a0000)
kernel32.dll => /cygdrive/c/Windows/system32/kernel32.dll (0x77180000)
KERNELBASE.dll => /cygdrive/c/Windows/system32/KERNELBASE.dll (0x7fefd1a0000)
msvcrt.dll => /cygdrive/c/Windows/system32/msvcrt.dll (0x7fefde00000)

$ x86_64-w64-mingw32-gcc --version
x86_64-w64-mingw32-gcc (GCC) 5.4.0
