This is on a fresh install of perl6 done via rakudobrew build moar && rakudobrew build panda.

$ which perl6
/home/cschwenz/.rakudobrew/bin/perl6
$ perl6 -v
This is Rakudo version 2015.12-362-g4cd2875 built on MoarVM version 2016.01-28-g2136293
implementing Perl 6.c.

It's probably a bug in Rakudo, I don't have this issue on a Rakudo from December

[jonathanstowe]

It's leaking the Failures, this behaviour changed a couple of days ago

[cschwenz]

Closing this issue as the merged fix resolves the original report. :-)
