Bug #133689 for Perl-LanguageServer: Error: Connection to server got closed.

I made a one-liner to tokenize the file, to try to isolate the problems: perl -e "use Data::Dumper; use Compiler::Lexer; my $source; { open my $fh, '<', $ARGV[0]; local $/; $source=<$fh>; } my $lexer = Compiler::Lexer->new(); my $tokens = $lexer->tokenize($source); print Dumper($tokens);" D:\Perl\Okid\test.pl This does not crash and produces the expected output. I tried something similar to invoke parse_perl_source, like this: perl -e "use Data::Dumper; use Perl::LanguageServer::Parser; my $source; { open my $fh, '<', $ARGV[0]; local $/; $source=<$fh>; } my $vars = Perl::LanguageServer::Parser::parse_perl_source(undef, 'x', $source); print Dumper($vars);" D:\Perl\Okid\test.pl This also did not crash, and produced what looks like correct output.
