Program received signal SIGSEGV, Segmentation fault.
So this really is a bash bug.
Notes:
- the file /home/fred/dlocate/dpkg-list_fr is a dlocate dpkg-list
file (I can send it to you if you want, it's about 133 kB bzip2-ed)
Please send a copy to the bug log.
Attached (bzip2 compressed).
I can confirm this crash under LC_ALL=fr_FR.UTF8.

Do you have another idea?
Is egrep the one segfaulting? You can do the same as before to build
a grep deb with debugging symbols, then just dpkg -i
../grep_deb. apt-get {--re,}install grep later if you wish.
It isn't completely clear to me how gdb would handle debugging the
grep; you might have to change the shell script to use
'gdb egrep $1 $DPKGLIST'
instead, or just dump $1 and $DPKGLIST to a file to fiddle with it
manually.
Hello Justin,
Thanks for your help.
I have tried to see if this was a problem with egrep and I have replaced
the egrep in the dlocate script with a simple cat $DPKGLIST. The
segfault also occurs. But it does not occur if I use a head $DPKGLIST.
What is the contents of $DPKGLIST? you should
echo $DPKGLIST /tmp/testgrep
The quotes are important. It occurs to me that, without quotes, you
could end up with $DPKGLIST being its own command, eg. if it contains
any of: ;` or such characters.. But this is perhaps also intentional
(and ` is still evaluated within quotes).
Sorry, I realize that I have quite unclear. $DPKGLIST is
/var/lib/dlocate/dpkg-list, this file contains the output of:
LINES=40 COLUMNS=200 dpkg -l * | sed -e '1,5d' -e 's/ */ /g'
using the current locale.
I have found that the problem only occurs if I send 276 lines (or more)
of text to the | while
Interesting..
If I try to execute the dlocate script with sh -x at the beginning
of the script, I need 373 lines to get the segmentation error.
If I execute the lines of the script at the command prompt, I get an
error with 22504. Here is the exact command that I used:
22504 is the number of lines of input, the line number, or a PID?
Argh, my fault again for being very unclear :-(. 22504 is the number
of lines which is causing a segmentation error in this cas.
$ echo $COLUMNS
150
$ ((fieldw=(COLUMNS-24)/4))
$ ((fieldd=COLUMNS-fieldw*2-6))
$ cat dpkg-list_fr | while read stat name ver descr; do printf %-2s
%-${fieldw}.${fieldw}s %-${fieldw}.${fieldw}s %-${fieldd}.${fieldd}s\\n
$stat $name $ver $descr; done
Does this crash cat, printf, or what? You can get rid of the cat by
rewriting as:
while read .. .. .. ..; do ..; done dpkg-list_fr
I suspect this is a bash problem with wide characters or such.
You are right. I have used the following procedure to debug my problem
(I try to be more precise than before):

locale, the segfault no longer occurs.
I don't really know how to get a backtrace from a builtin bash
command. So any advice would be welcome.
apt-get source bash dpkg-dev
cd bash-...
DEB_BUILD_OPTIONS=nostrip dpkg-buildpackage -rfakeroot
gdb --args ./debian/bash/usr/bin/bash dlocate -l openoffice
Rather gdb --args ./debian/bash/bin/bash dlocate -l openoffice
(without /usr). However, this does not help to get a backtrace file:

Bug#374565: bash: printf from dlocate segfaults with fr_FR.UTF-8 locale
Package: bash
Version: 3.1-4
Severity: normal
Tags: l10n
Hello,
Here are the steps to reproduce the problem:
- have (and use) an fr_FR.UTF-8 locale
- install the dlocate package
- generate dpkg-list (localized) using this command (from
/etc/cron.daily/dlocate):
LINES=40 COLUMNS=200 dpkg -l * | sed -e '1,5d' -e 's/ */ /g'
/var/lib/dlocate/dpkg-list
- use dlocate like this:
$ dlocate -l openoffice
The final lines read:
$ dlocate -l openoffice
[...]

%-${fieldd}.${fieldd}s\\n $stat $name $ver $descr;
done
$
If I change the printf command with /usr/sbin/printf, the segfault no
longer occurs. If I generate the dpkg-list file with the C locale, the
segfault no longer occurs. If I execute the dlocate command with the C
locale, the segfault no longer occurs.
I don't really know how to get a backtrace from a builtin bash
command. So any advice would be welcome.
Greetings,
Fred
