Confirmed on 2017.04.3-293-ga7c23aa Rakudo on Win10 Pro. Crashes almost
instantly. Task manager tells me I still have 6.4GB of free memory.
Tried in command prompt run as administrator as well; same issue.
The same script works fine on 2017.05-132-gc5398c8 in a Bodhi Linux 4GB RAM VM
running inside that Win10 and uses 229MB of RAM:
$ /usr/bin/time ./perl6 foo.p6
Starting...
Array initialized.
