Bug#647642: hurd: ^C trips assertion: intr-msg.c:389: _hurd_init_rpc_mach_msg: Assertion `m->header.msgh_id == msgid + 100' failed.
Package: hurd
Version: 20110519-3
Hi,
Glancing at buildd.debian.org today, I noticed that the git testsuite
has not been passing on hurd for a while. Oh. Running the test suite
by hand, we learn that t9100 and some other tests fail, because the
"svn import" command is completely broken:
$ svn import -m 'some message' directory file://$(pwd)/target
svn: Couldn't perform atomic initialization
svn: disk I/O error
svn: disk I/O error
But I digress. In order to investigate that, I wanted a copy of a
reasonably-recent version of subversion, with debugging symbols. So:
$ svn checkout svn://svn.apache.org/repos/asf/subversion/trunk subversion
Which, um, just sits there. Ok, so switch VTs and attach to it with gdb:
$ ps | grep svn
5135 3 S 0:00.07 svn checkout svn://svn.apache.org/repos/asf/subversion/t
5140 1 S 0:00.00 grep svn
$ gdb -p 5135
GNU gdb (GDB) 7.3-debian

[more boilerplate snipped]
Attaching to pid 5135
[New Thread 5135.1]
[New Thread 5135.2]
Let's see what it's up to:
(gdb) continue
Continuing.
warning: Can't wait for pid 5135: No child process
Now we return to the original VT and hit ^C.
^Csvn: intr-msg.c:389: _hurd_intr_rpc_mach_msg: Assertion `m->header.msgh_id == msgid + 100' failed.
Aborted
For completeness, I should mention what gdb sees, too.
warning: Pid 5135 died with unknown exit status, using SIGKILL.
Process terminated with SIGKILL, Killed.
The program no longer exists.
(gdb) quit
Reproducible. Trying to interrupt the "svn checkout" with ^C without
gdb attached to it does nothing, by the way (it just continues
hanging). ^\ kills it, though.
If there's any information I can provide to help track this down, just
ask.
Thanks,
Jonathan
