Package: gawk
Version: 1:3.1.5.dfsg-4
Severity: important
I got SEGABRT from gawk on amd64 with LANG is UTF-8.
First, create data file.
$ LANG=C dpkg -l > dpkg-list.txt
$ head dpkg-list.txt

Description
+++-=================================-===============================-======================================================
ii 915resolution 0.5.2-9
resolution modification tool for Intel graphic chipset
ii a2ps-perl-ja 1.45-4 perl
version of Miguel Santana's a2ps (supports KANJI)
ii acpi 0.09-1 displays
information on ACPI devices
ii acpi-support 0.90-2 scripts
for handling many ACPI events
ii acpid 1.0.4-5 Utilities
for using ACPI power management
And, I try following commands:
$ export LANG=en_US.UTF-8
$ /usr/bin/gawk '{print length($2)}' dpkg-list.txt > /dev/null
*** glibc detected *** double free or corruption (fasttop): 0x000000000055cb60
***
Aborted
following commands is OK (no errors):
$ /usr/bin/gawk '{print $2}' dpkg-list.txt > /dev/null
$ /usr/bin/gawk '{print length($1)}' dpkg-list.txt > /dev/null
$ LANG=C /usr/bin/gawk '{print length($2)}' dpkg-list.txt > /dev/null
I use LANG=ja_JP.UTF-8 env., segfaults too.
I attached file that following command output:
$ strace -f -F -o awk-trace.txt /usr/bin/gawk '{print length($2)}'
dpkg-list.txt > /dev/null
