The perl6 stand-alone binary chokes on chromatic's mmd example (http://www.oreillynet.com/onlamp/blog/2008/04/multiple_dispatch_now_please.html) under linux/x86. The bug was exposed in r26173, but the root cause is probably deeper. It looks easy to reproduce, but I can certainly provide more information if as needed.
