Package: msort

When trying to sort an UTF-8 file with 2 sort keys in a bash script, I get
the following error:

/home/fevrier/bin/test-msort.sh: line 5: 14067 Abandon msort -l
-d '\t' -n 1 -s fr_FR.UTF-8 -n 2 -s
fr_FR.UTF-8 test1.txt
----------------------------------------------------------------------
Using the same command from the command line does not reproduce the error.
Here is the script that reproduces the problem:
----------------------------------------------------------------------
#!/bin/bash
set -x
msort -l -d '\t' -n 1 -s fr_FR.UTF-8 -n 2 -s fr_FR.UTF-8 test1.txt
----------------------------------------------------------------------
I get no error if I remove the "-n 2 -s fr_FR.UTF-8" part.
I had this problem with the Debian stable version of msort. Upgrading
msort to the version in testing has made no difference.

I can repro this in lenny.
I can't repro this with
msort_8.52-1.2_amd64.deb
+ libicu42_4.2.1-3_amd64.deb
+ bookworm
BUT I do see

I can't repro this with msort 8.53-2.3+b2 on bookworm (with bookworm deps),
so this got fixed somewhen between lenny and bookworm.
