Package: dpkg
Version: 1.14.16.1
Severity: important
Starting asterisk using start-stop-daemon:
# start-stop-daemon --start --group asterisk --pidfile
/var/run/asterisk/asterisk.pid --exec /usr/sbin/asterisk -- -U asterisk
Segmentation fault
The problem is the "--group asterisk":
Using GDB (don't know how to get debugging symbols for start-stop-daemon
:-/):
# gdb --args start-stop-daemon --start --group asterisk --pidfile
/var/run/asterisk/asterisk.pid --exec /usr/sbin/asterisk -- -U asterisk
GNU gdb 6.7.1-debian
(no debugging symbols found)
Using host libthread_db library "/lib/libthread_db.so.1".
(gdb) r
Starting program: /sbin/start-stop-daemon --start --group asterisk

Starting without "--group asterisk" works (but is not a fix, of course)
