Including Chart::GGPlot conflicts with Parallel::ForkManager

[ryan-preble]

I am currently running Strawberry Perl 5.32.1 on Windows 11 22H2. I am writing scripts to do some bulk data processing which necessitates parallelism. I have discovered that including Chart::GGPlot and any module in Parallel causes failures in forking. The issue is simple to replicate. The following code fails to run:

`use Parallel::ForkManager;
use Chart::GGPlot;
use Autoloader;

my $pm = Parallel::ForkManager->new(3);

$pm->run_on_finish(
sub {
my ($pid, $exit_code, $ident, $exit_signal, $core_dump, $return_ref) = @_;
my $returned = ${$return_ref};
print "Child with ", $returned->{"filename"}, " finished.\n";
}
);

LOOP:
foreach my $file (@argv) {
my $pid = $pm->start and next LOOP;
print "Starting with $file \n";
my $return_data = {};
$return_data->{"filename"} = $file;
$pm->finish(0, $return_data);
}
$pm->wait_all_children;

print "Is this gonna work???\n";`

Note that no error is immediately thrown, and the code simply terminates early. However, commenting out the usage of Chart::GGPlot allows the code to execute to completion. I can also try to fish out error messages if that would be helpful.
Thank you!

I've narrowed it down to autobox which is used by Data::Frame. Raised chocolateboy/autobox#16 and dluxhu/perl-parallel-forkmanager#38

Also confirmed it's good on Linux.
