This segfault looks very similar to the issue reported as Trac #26 (
https://trac.parrot.org/parrot/ticket/26 ), I believe they are the same
issue.

@Reporter, which linux distro are you using?  Unfortunately I can't
reproduce this on my gentoo x86-64 box (I just tried with r33853).  If
you are using Ubuntu, that may be helpful in figuring out what the
difference is.  I do notice I have a different version of libicudata
than you do, likely other things differ as well.

Thanks,

Mark
