Package: bash
Version: 5.1-2+b3
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Some bash scripts failed.
Here is a script reproducing the bug:
-----
#!/bin/bash
if [ "$FIRST_LEVEL" != "no" ] ; then
export FIRST_LEVEL=no
for i in {1..100} ; do
$BASH $0 $i || exit
done
exit
fi
s="§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§"
s="$s$s$s$s$s$s$s$s$s"
s="${s:0:256}"
prefix=1
for prefix in 1 ; do
str="1$s"
s1=$(echo "$str")
s2=$str
if [ "$s1" != "$s2" ] ; then
echo $LANG $prefix $1
echo ${s1:256} | od -t x1c
echo ${s2:256} | od -t x1c
exit 1
fi
done
----
With LANG=en_US.utf8 it shows the bug.
With LANG=C it produces no error
* What exactly did you do (or not do) that was effective (or
ineffective)?
If i put LANG=C in the script it run as expected.
I have tried with upstream bash and found:
if I use --without-bash-malloc on configure I get the bug.
if I do not use --without-bash-malloc on configure the bug disappears.
My gcc: gcc (Debian 10.2.1-6) 10.2.1 20210110
My libc6: Version: 2.31-13
The bug do show at every run, that why I try 100 times in the script.
