Hello,

I have just installed cups-dbg. Which add no debug information to cupsd.
Nevertheless I have started cupsd in gdb:

Current directory is /usr/sbin/
GNU gdb (GDB) 7.0.1-debian
Copyright (C) 2009 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later

This GDB was configured as "x86_64-linux-gnu".
For bug reporting instructions, please see:
<http://www.gnu.org/software/gdb/bugs/>...

warning: The current binary is a PIE (Position Independent Executable),
which
GDB does NOT currently support.  Most debugger features will fail if used
in this session.

Reading symbols from /usr/sbin/cupsd...(no debugging symbols found)...done.
(gdb) run
Starting program: /usr/sbin/cupsd

Program received signal SIGUSR1, User defined signal 1.
0x00007ffff64d5c60 in ?? ()
(gdb) up
#1  0x00007ffff64d5ae0 in ?? ()
(gdb) up
#2  0x00007ffff7fc2560 in ?? ()
(gdb) up
#3  0x0000000000000200 in ?? ()
(gdb)

Which seem to result in:

Feb 21 11:58:18 acer-ilzleite kernel: [ 1652.003042] cupsd[7511]:
segfault at 0 ip 00007ffff64b27c1 sp 00007fffffffccc8 error 4 in
libc-2.10.2.so[7ffff6439000+14a000]


The SIGUSR1 was also reported in #549050, but interpreted as SIGHUP.
So the 2 bugs could be renamed and merged.


Greetings
	Juergen
