Segfault in Inline::Python.new.run

[moritz]

I've tried to write a test file about passing arrays to python functions:

#!/usr/bin/env perl6

use v6;
use Inline::Python;

use Test;
plan 2;

my $py = Inline::Python;

$py.run: q:to<EOP>;
def test_array(a):
    return ','.join(a)

def nested_join(*args):
    return ','.join([';'.join(e) for e in args])
EOP
is $py.call('__main__', 'test_array', ['a', 'b']), 'a,b', 'simple array';

is $py.call('__main__', 'nested_join', ['a', 'b'], $['c', 'd']),
   'a;b,c;d',
    'can pass arrays to slurpy argument';

It segfaults in the run method, afaict:

Feel free to use the test file if it makes sense :-)
