  If "make perl6" fails, try this instead:

  cd languages/perl6/
  make ../../parrot perl6.pbc -e 'say "hi"'

  That doesn't build an executable, just a bytecode file (perl6.pbc). It's not so easy to run, but it works more reliably.

  (The executable is really just as wrapper that links parrot and contains the byte code. Sadly that wrapper isn't very table yet)

    It's almost exactly the same code as the parrot executable, with two differences. First, it doesn't load external bytecode. Second, it performs a full shutdown of the Parrot interpreter when the process exits.

    The latter occasionally finds memory management errors. I enabled it for that reason -- but these are rare. I've seen (and fixed) one in the past two months.

      If the executable wrapper mostly reveals underlying problems, and doesn't
      cause too many on its own, maybe we should use it for running the tests.

      I already get some memory management failures (at least sometimes) in the
      rakudo tests, it would be a good idea to expose them.

        Add the --leak-test flag to parrot for the same effect; that option enables the same internal option as the fakecutable.
