On one implementation (gcc, glibc, 64 bits), it *can* "work":

```
#include <stdio.h>
int main(void) {
    unsigned long x = 123456789;
    printf("sizeof (unsigned) = %zu\n", sizeof (unsigned));
    printf("sizeof (unsigned long) = %zu\n", sizeof (unsigned long));
    printf("x = %u\n", x);
}
```

The output on my system (after some compiler warnings):

```
sizeof (unsigned) = 4
sizeof (unsigned long) = 8
x = 123456789
```

Apparently printf tries to grab a 32-bit value and happens to get
the low-order 32 bits of the 64-bit value that was passed.  A value
exceeding LONG_MAX is not printed correctly, but in principle it
could be.

Of course I do not advocate doing this other than as a test of an
implementation's behavior.

J.B.S. Haldane famously said that "The Universe is not only queerer
than we suppose, but queerer than we can suppose."  The same is
true of undefined behavior.
