Test 28 in t/pmc/filehandle.t is that weird test which, as I've reported

4294967286 isn't -10. There's a sign extension problem somewhere.
Presumably as you're on PPC Darwin you're still on an version of OS X
with ktrace and kdump. I guess that they'd show a similar problem with
(not) -10
$> ktrace ./parrot t/pmc/filehandle_28.pir
$> kdump | tail -100 > tail_t_pmc_filehandle_28_pir_ktrace_dump
So here (attached) is the last 100 lines of the kdump. I can send Nick
or anyone else who can decipher this the full output.
Thank you very much.
