Resending, likely caught by filters.
Hi,
Please do a link time test instead, I am not getting this error and
would like to keep stack protector on.
The test case below will trigger ___stack_chk_guard to emit.
int main(){
int i = 0;
char a[1000];
while(1){
a[i] = 0;
i++;
}
}
"i686-w64-mingw32-gcc -D_FORTIFY_SOURCE=2 -fstack-protector --param
ssp-buffer-size=4 -v" shows that libssp is already added.
Alternatively, to include __stack_chk_fail, use:
extern void __stack_chk_guard();
extern void __stack_chk_fail();
int main(){
void (*ssp[]) = {
__stack_chk_guard,
__stack_chk_fail
};
return 0;
}
