Hello!
Last night, while I was compiling GNU Mach, I got the following assertion
failure:
#v+
ext2fs.static: thread_cancel.c:55: hurd_thread_cancel: Assertion `!
__spin_lock_locked (&ss->critical_section_lock)' failed.
#v-
GNU Mach did not enter the kernel debugger, but was just hanging instead.
I didn't do anything special, so I don't know how I could reproduce it.
Sadly this concides with other reports of the same assertion failing (see
the attached messages,
<URL:http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=46859> and
<URL:http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195360>).
Regards,
Thomas

hurd_thread_cancel trips assertion |

Package: libc0.2
Version: N/A
Severity: critical
Note: I'm sending this report such that this bug will enter the Debian
BTS. The bug has been discussed before on bug-hurd and Roland will
(eventually) look into it. I don't think any immedeate action needs
to be taken by any other party. A summary of the discussion on
bug-hurd follows.
I caught the term server on /dev/console failing the following
assertion in hurd_thread_cancel() (hurd/thread-cancel.c:46):
assert (! __spin_lock_locked (&ss->critical_section_lock));
Since there is no guarantee that the target thread is not in a
critical section, there is obviously something wrong here.
Thomas suggested that there is no need to take the critical section
lock. I believe that taking the critical section lock is necessary to
prevent the target thread from entering a signal handler. Roland will
look into the problem.

Anybody know what became of this bug
<URL:http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=46859&repeatmerged=yes>?
Is it fixed/still reproducible/unknown?

I got a different Hurd crash than normal. I don't have any more
information than this, sorry. This occured when I was doing an
autobuilder run:
extfs.static: thread-cancel.c:55: hurd_thread_cancel: Assertion `!
__spin_lock_locked (&ss->critical_section_lock)' failed.
The crash is unusual in that the computer didn't reboot like normal,
it was still sitting here when I got up.
Tks,
Jeff Bailey

Mark, (Heya, long time)
I'm just cleaning out the glibc BTS. I pinged Roland about this bug
earlier today, and he indicated that he had no intention of touching
this code until he did a massive overhaul on it.
At a minimum, I'd like to downgrade this bug to 'normal'. Ideally,
I'd like to close it, since it 1) Will never be fixed in a way that's
meaningful to this bug and 2) it's not in a place that Roland ever
looks anyway.
It might be best to submit this in upstreams gnats database to meet
your original need.
Lemme know.

learning from failures is nice in theory...
but in practice, it sucks :)

After some builds of oskit and gnumach I got the following assertion
failure:
ext2fs.static: thread-cancel.c:55: Assertion `! __spin_lock_locked
(&ss->critical_section_lock)' failed.
libc0.3 is 2.3.1-5.
P.S. The most interesting part is that while compiling oskit, I browsed
a hurd mailing list and the assertion failed just after I hit Enter to
view #116317 ;-)
