Such as:
// x.c
#include <stdio.h>
int main(void) {
char x[] = "abc";
printf("%s\n", x);
return 0;
}
and using GCC compile it:
➜ gcc x.c -v
......
/usr/libexec/gcc/x86_64-redhat-linux/5.1.1/cc1 -quiet -v x.c -quiet -dumpbase x.c -mtune=generic -march=x86-64 -auxbase x -version -o /tmp/ccqowh4f.s
......
as you see, GCC not enabled the -fstack-protector by default. And in Ubuntu:
➜ gcc x.c -v
/usr/lib/gcc/x86_64-linux-gnu/4.6/cc1 -quiet -v -imultilib . -imultiarch x86_64-linux-gnu x.c -quiet -dumpbase x.c -mtune=generic -march=x86-64 -auxbase x -version -fstack-protector -o /tmp/cc0aswkw.s
the enabled the -fstack-protector by default.
