Package: libc6
Version: 2.7-6
Severity: important
Investigating a problem with asterisk not starting, I found that
start-stop-daemon was segfaulting when fed a group.
/etc/nsswitch.conf has not been modified.
/etc/group starts with the standard
root:x:0:
daemon:x:1:
bin:x:2:
sys:x:3:
adm:x:4:
tty:x:5:

This pointer is NULL.
Quoting the manpage:
The user argument must be non-NULL.
The bug is therefore not in the glibc, but in dpkg. Reassigning the bug
to dpkg.

Please hint glibc/2.7-6
Hi, glibc/2.7-6 is ready to go into testing. It fixes bugs that are present in the testing version (and most notably an RC bug), and hasn't any known regression. Could you please hint it?
