Gregor forwarded this as
https://rt.cpan.org/Ticket/Display.html?id=85999 -- nevertheless it
looks quite a lot like a modern incarnation of
https://rt.cpan.org/Ticket/Display.html?id=40287

The failure seems to be always in t/04-fork.t, either after test 8 or
after test 15. Sometimes the test also passes, so there seems to be
some random part in it as described in
https://rt.cpan.org/Ticket/Display.html?id=40287

I seem to be able to reduce the probability for hanging (but not avoid
it completely) if I comment out the lines _after_ "$output = slurp
$testfile;" (i.e. the line where $output is first accessed) in those
tests which included code references.

You can easily output the return value of slurp before it returns it,
but accessing it after slurp has ended, fails in approx. half of the
cases.

Replacing the included slurp implementation (in t/Util.pm) with the
implementation of File::Slurp does not seem to make a difference.

So far my findings. Didn't find a reliable solution, though.
