Oops, looks like we have a typo, I forgot to reset to first ulong. Patch

This is expected. set_ith_ulong replaces exactly one ulong, and ulongs
are likely 64bits on your machine (but we always print using 32bit masks
to be arch-independent). That's why the third and fourth 32bit masks are
replaced above (with 0xdeadbeef and nothing respectively).
