While trying to golf spectest failures in S17-supply/syntax.t I found some really weird behaviour.
Consider the following program 'S17-supply_syntax_golf.p6':

====
use v6;

for ^1 { my $foo };

my $a = supply { };
my $b = supply { };

I'm trying to debug the following NullPointerException:

$ perl6-j -e 'CallFrame.new.perl'
java.lang.NullPointerException
  in block <unit> at -e line 1

For some reasons iterating over the values of a specially constructed Stash (using nqp::iterval) does not work. I get the following output with the program below.

$ perl6-m iterating.p6  # works fine

There are different issues with Rakudo on JVM after the merge of 'relocateable-precomp'.
I compared an installation on the merge commit e8fd55bbe6 with a second installation
on that commit plus 'git revert -m 1 e8fd55bbe6'.

* a lot of new failing tests in S10-packages/precompilation.rakudo.jvm (some others where
  fudged before): 2-4, 7-21, 24-26, 28-30, 32, 38, 39           

* test for RT #114354 fails (S06-other/main.t aborts), because 'sub MAIN' in
  t/spec/packages/HasMain.pm (line 5) is called with @*ARGS containing five elements
