The segfault only occurs when running ./perl6, not when running
../../parrot perl6.pbc.

That's because all fakecutables set the flag which tells Parrot to destroy
everything at shutdown. If you add the --leak-test or --destroy-at-end flags
to the ../../parrot invocation, you'll see the same behavior. (No one else
ever uses those flags, which is why I enabled the behavior for all
fakecutables.)
