in thread Fork and creating a thread exits the process

fluks,

I have 64-bit Strawberry 5.30, and it has no trouble correctly running fork:

#!perl use strict; use warnings; use feature 'say'; use Config; BEGIN { $| = 1; # autoflush say "perl $^V, uname = ", $Config{myuname}; } END { say scalar localtime, "\tprocess $$ is exiting"; } my $pid = fork(); if($pid==0) { say scalar localtime, "\tI am the child $$"; exit; } say scalar localtime, "\tI am the parent $$"; __END__ perl v5.30.0, uname = Win32 strawberry-perl 5.30.0.1 #1 Thu May 23 12: +20:46 2019 x64 Fri Jul 31 06:32:31 2020 I am the parent 10128 Fri Jul 31 06:32:31 2020 process 10128 is exiting Fri Jul 31 06:32:31 2020 I am the child -5108 Fri Jul 31 06:32:31 2020 process -5108 is exiting

What happens if you run the same code?

    This test works on 32bit Strawberry. And to be clear, my program works with that Perl version too, both with forking and threads, it seems to be the only Perl that it works on.

      This test works on 32bit Strawberry.

      But does it work for you on 64bit? I ask this because you said,

      tested now with Strawberry 64bit and I wasn't able to get it work. But I tried again starting with a fresh 32bit version at that still does work.

      With my code, I was showing a fork-based program that was known-working for me in 64bit, and wanted you to see whether or not my code worked on your 64bit Strawberry.

      32bit Strawberry ... seems to be the only Perl that it works on

      I do not see that limitation. The code I posted works for me on both 32bit and 64bit.

        Sorry for the late reply.

        The test script did work on a 64bit Strawberry too.
