If a core dump isn't obtainable, then it's possible to execute the crashing process under the debugger, if the crash can be reproduced. In the case of shibd, you can do something like this as root:
| Code Block |
|---|
gdb /usr/sbin/shibd |
...
(gdb) set args -F |
...
(gdb) run |
You should be able to trigger the crash and see it caught by the debugger, at which point a stack trace can be obtained.
