Cannot su or sudo

While I'm waiting for the other problems to recur, I've got another fun one:

buildd@hurd:~$ su
(Wait forever)

^C still works.

buildd@hurd:~$ gdb su

Can't fetch registers from thread 3: No such thread
(gdb) info threads
Segmentation fault

I can't set a breakpoint on main...  Perhaps my gdb is screwed up.
I'll try building a new one tommorow.

`Oskuro' reported the same problem earlier today, so I suspect it's
probably eventually reproducable.  I noticed it when the build hung on
an sudo.

I don't actually know what happens during an 'su' on the Hurd, so I'm
not sure what to check after this.

I just checked: From the console I can login as root, and I can login
as buildd.  However, I cannot su - so I don't think this is just my
ssh session that's screwed up.  I'll try to leave the box in this
state for as longas I can.  If it's just gdb screwing up, maybe a new
one will tell me more.

I'll keep you posted.

Abandon the search for truth; settle for a good fantasy.
