1593	parrot puts an invalid value in a register when vtable override does not return as expected	NotFound		"This shows the problem:

{{{
$ cat override.pir
.sub main
    $P0 = newclass ['Foo']
    $P1 = new $P0
    $P2 = $P1[0]
    say 'in main'
    print $P2

.namespace [ 'Foo' ]

.sub get_pmc_keyed_int :vtable
    .param int i
    say 'Foo overrides'
.end
$ parrot override.pir

Segmentation fault (core dumped)
}}}

Oddly, it doesn't segfault in a non optimized build.
