Bug#72319: Empty Executable File Forces Hurd Reboot

[Roland McGrath]

I am guessing it is the exec server that is crashing.  When it reboots,
do you see any messages?

Try this:

# gdb /hurd/exec
(gdb) set noninvasive
(gdb) attach EXEC-PID

where EXEC-PID is the pid of /hurd/exec you see in ps -A.

then produce the bug, e.g.:

(gdb) ^Z
Suspended
# (sleep 5; touch test ; chmod a+rx test; ./test) &
# fg

and perhaps you will see some indication of the lossage.
If you can do a backtrace in gdb, that will be good.
