The crash is in calling .perl on the hash I think, printing the scalar worked.

As I read from the IRC log http://irclog.perlgeek.de/perl6/2012-03-16
I need to install libicu-dev and rebuild parrot and rakudo to solve this issue.
It indeed solved it.

I am still wondering what is the issue there? Having

    $s = 'Gábor'

does not yet trigger the crash but the Hebrew letters do.

The difference is that á fits into Latin-1, and there's some support for 
characters in the Latin-1 range hardcoded into parrot/nqp/rakudo (dunno 
which part exactly) which works even in the absence of ICU.
