Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 47236244385456 (LWP 24325)]
0x00002af6098b097a in Parrot_Iterator_shift_string ()
from /home/ihrd/parrot/blib/lib/libparrot.so.0.8.1

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
