<pre>I believe this program is required to output "0" because it's comparing
pointers to two separate stack allocated objects. However, compiled with Clang
3.5, it outputs "1" because the const char array is being promoted from
automatic storage to static storage.
#include <iostream>
bool Test(const char *s = 0) {
const char x[] = "test data";
return s ? x == s : Test(x);
}
int main() {
std::cout << Test() << std::endl;
}</pre>
