Test failures with Strawberry Perl 5.30.1

[SteelBlueVision]

I am getting the following failures when trying to install v. 1.26 with Strawberry Perl 5.30.1 on Windows 10:

Investigation

Did a build manually, and it seems that 04_capture.t when executing the Line 25:
my $output = capture($output_exe);

..., seems to read from stdin without echo, instead of executing the command $output_exe and reading its output. On my system during the test, the value of $output_exe is:
C:\strawberry\perl\bin\perl.exe output.pl

I went deeper and found that in sub _win32_capture:
$command contains: C:\strawberry\perl\bin\perl.exe output.pl
@args is empty!

So, later when the exe file is parsed out into $exe the output.pl part is lost and, because @args is empty, instead of the intended call to the output.pl script:
C:\strawberry\perl\bin\perl.exe output.pl
..., we get:
C:\strawberry\perl\bin\perl.exe
..., which just sits there when executed and waits for you to type in a perl script interactively.

Thanks for the report. I have just been assigned as a co-maintainer of IPC-System-Simple. I don't have access to a Windows development machine, nor do I have recent experience with code development on Windows. So I'm not at all surprised that we're having problems on mswin32. I cannot promise a quick fix, but when I have access to Windows I will re-examine your report.

Thank you very much.

Noting a somewhat larger set of failures in a run on Strawberry Perl here:

(first CPANtesters report received in a long time).

Can you try the following branch in the github repository and see if it reduces the number of test failures?

Thank you very much.

I believe that we have addressed this issue in CPAN versions 1.28 and later (currently, 1.29). Can you confirm?

Thank you very much.

I believe that this issue may be resolved in IPC-System-Simple version 1.30, just released to CPAN. Can you confirm?

Thank you very much.
