Rakudo r35481 reacts badly to a printf wherein the variables needed
are fewer than the variables available.

$ perl6 -e 'printf("%s")'
Null PMC access in get_string()
[...]

Same error with sprintf so test added to /t/spec/S32-str/sprintf.t.

The RT System itself - Status changed from 'new' to 'open'

And now it dies with an error message again, but this time, the message
is informative; see #​74610.

Hello,

Oddly, this is exactly the same symptom that was reported and resolved in
2009 in bug #​62316. It looks like it sneaked back into the latest version
of Rakudo.

$ perl6 -e 'printf "%s"'
Null PMC access in get_string()
  in sub sprintf at src/gen/CORE.setting​:2471
  in sub printf at src/gen/CORE.setting​:2476
  in block at -e​:1

$ perl6 -v
This is perl6 version 2013.03 built on parrot 4.10.0 revision RELEASE_4_10_0

Niecza rejects this with a more appropriate "Unhandled exception​: Not
enough arguments for this format string".
