I found a small piece of code that reproduces the "Null PMC access in
type()" error:

sub f(Int $n){
    if ($n >= 0 ){
        f($n-1);
    }
}
f(0);

produces the above error on parrot + rakudo r29207, Debian GNU Linux
i386 32bit.

An even smaller example is
sub f (Int $n) { f($n-1) }; f(0)
except that this one would loop infinitely if it weren't for the null
PMC access.
