Hi Achim,

> The stacktrace is useless, but if you run this under strace you'll also see a message that doesn't make it to the output otherwise:

That arises from the subsequent print statement, which is never reached under cygwin.

Alternative command that eliminates that warning:

perl -MTerm::ReadKey -we 'my $input = ""; open(my $stdin, "<", \$input) or die "failed to open: $!"; local *STDIN = $stdin; ReadMode "raw"; my $response = ReadKey(1, \*STDIN); ReadMode "normal"; if(defined($response)) { print "Got \"$response\"\n"; } else { print "Got undef\n"; }'

> Please report this upstream.

To whom would that be? Perl devs?

Kind regards,
Luke
