Bug Description

Hello

I seem to have come across an abnormality, with the Ubuntu ( DEBIAN ) KORN Shell package [
Version AJM 93u+ 2012-08-01 ] when it is running under the Windows Subsystem for Linux.

Basic inbuilt arithmetic and test functions appear to be broken for long lengths under WSL

<-- Beging Test Script -->

#!/bin/ksh

Y=1
Z=1
X=7680072911
C=1
until [ ${C} -eq 50 ]
do
typeset -i -l Y=$(( ${Y} + ${Y} + ${X} ))
typeset -i -l Z=$( echo “(${Z} + ${Z} + ${X})” | bc )
print "C=${C},Y=${Y},Z=${Z}, $( [ ${Y} -ne ${Z} ] && print Error || print Ok )"
C=$(( ${C} + 1 ))
done

<-- End Test Script -->

The test script returns significantly different results on standard KORN Version AJM 93u+ 2012-08-01 running under Ubuntu, Darwin, etc as opposed to running under the WSL.

<-- Ubuntu, Darwin, -->

Has anyone else come across abnormalities effecting the standard functionality of the KORN shell running under WSL ???

Is this a DEBIAN / Ubuntu bug or a windows WSL bug ?

Logged issue VIA https://github.com/Microsoft/WSL/issues/ as :

Inbuilt KORN Arithmetic & Test functions broken under Windows Subsystem for Linux #4244

Referencing : https://bugs.launchpad.net/ubuntu/+source/ksh/+bug/1818596

The bigger issue here is the power that M$ is waiving with the WSL ports of Linux. They are modifying the runtime results of critical components of Linux, which either by unintelligent design or mistake, leads to serious unexpected results, confusing the end users and pissing off the developers and wasting their time !

It would make for an interesting legal case against M$ by all the Linux Developers for breaching the copyrights of their code and hacking their code by modifying the runtime environments to produce irregular results.
