Hm, I completely didn't see that it was a union instead of a struct. I
still think my fix is actually correct though. Now that you point out
the union, I see that my change is equivalent to just removing the '&'
char.
- memcpy(&rd->key, &fd.key, sizeof(struct hfs_cat_key));
+ memcpy(&rd->key, fd.key, sizeof(struct hfs_cat_key));
We don't want to copy sizeof(*fd.key) because that would write past the
end of the destination struct.

I don't understand what you mean here.
