Markus,
I'm not sure, but i think you may need to specify a core file at
startup, or attach to a process that you want to debug...
process id of program to debug = 4128
user@host:~$ gdb
(gdb) attach 4128
Attaching to process 4128

(gdb)
now try your catch... I'm not sure if that helps or not, but good luck
:-)
