To reproduce: 1. Save https://gist.github.com/bbkr/19ba6903358445410812bc09b0c0ec9c as Foo.pm 2. rm -rf .precomp/ 3. perl6 -I. -e 'use Foo' Result - module never gets compiled, moar takes 100% CPU. OS X 10.10.5, Rakudo 2016.03. Maybe it has something to do with warning groupping mechanism? Valid signatures or less different signatures compile just fine. BTW: I get reproducible error on OS X but it works on Linux (I've tried to increase amount of different signatures up to 20 but all I got was small linear compile time increase, no infinite locks).
