You're right, of course. I apparently pasted the wrong version of the file in
the opening comment. It definitely should have been a `long`.
In my original test case, the struct looked like this:
```
struct span {
int* p;
unsigned long long size;
};
```
But two longs also work.

Yes, but ARM32 puts the arguments of f() on the stack, just to immediately load
them from the stack.
If wanted/needed, I can open a different bug report for ARM32.
