Inbuilt KORN Arithmetic & Test functions broken under Windows Subsystem for Linux #4244
Comments
#830. Will be okay if you go WSL2. |

@therealkenc I think you are missing the underlying points. The previous KORN issues are not related to long lengths. Why have you flagged it as a duplicate ? https://github.com/microsoft/WSL/issues?utf8=✓&q=korn+ |
I suppose that could happen in principle. But not in this case.
You're right, the previous KORN tickets are not related to long lengths. #830 is the duplicate ticket causing your long length issues with KORN. Your remedies are (a) Use WSL2, (b) Stick a Me I'd go with (a). But it is late on Saturday night and I'm still awake, so (b) for the time sink value.
Because this issue is dupe #830. |

Easier to go with running Linux in a VM ignoring all the other bugs in WSL, WSL2, Windows10. |
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
Refer : https://bugs.launchpad.net/ubuntu/+source/ksh/+bug/1818596
for analyse and WSL version / confirmation of bug.

Reproducible with WSL on Insider build 18917
<-- Beging Test Script -->
#!/bin/ksh
Y=1$( [ $ {Y} -ne ${Z} ] && print Error || print Ok )"
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},
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.
