{{{
aus...@andlinux:~/kakapo$ cat test.nqp
my %hash;
%hash<key> := 1;
#my $x := ~ %hash<key>;
my $y := ~ %hash<key> // 'r';
}}}
Produces:
{{{
aus...@andlinux:~/kakapo$ parrot-nqp test.nqp
Null PMC access in set_string_native()
current instr.: '_block11' pc 0 (EVAL_1:6)
called from Sub 'parrot;PCT;HLLCompiler;eval' pc -1 ((unknown file):-1)

}}}
The bad part of the code seems to be:
{{{
vivify_13:
set $S21, $P20
set $P18, $S21
defined $I23, $P18
if $I23, default_22
new $P24, "String"
assign $P24, "r"
set $P18, $P24
}}}
Note here the use of $P18, which has never been initialized.
