1) ignorecase.t - reduced to bare bones.
On a 64-bit system that lacks ICU;
Running this code:
    use v6;
    $_ = 'a';
    #m:i/δ/;
    m:i/ß/;
gives this (appropriate) error:
    ===SORRY!===
    no ICU lib loaded
Uncommenting line 3 changes the error to:
    ===SORRY!===
    Confused at line 3, near "m:i/\u03b4/;\nm:"

I do not know why the two lines produce different errors, but I  
suspect it is a bug.

2) dash-e.t - reduced a single line.
On a 64-bit system that lacks ICU;
    my $c = "\c[LATIN SMALL LETTER A WITH DOT ABOVE]";
This produces the same error (segfault) as the whole dash-e.t file.
When I run it this way:
    parrot_install/bin/parrot perl6.pbc d1.p6
I get:
    ===SORRY!===
    attempt to access code outside of current code segment


I do not have a 32-bit system that lacks ICU,
but when I ran both examples on 32-bit Darwin with Parrot configured -- 
without-icu,
I get the exact same results.
Therefore, I think you can move this from 64-bit issues, to no-ICU  
issues.
Perhaps this will allow a larger pool of people to assist.
