Hi Rodrich,
Thank you for inform me of this finding. Just wondering maybe it is possible to
update PAR::Packer soon since wrap packed script into a BEGIN block or into
BODY
block seems do not need much change? and the pack function and parallel process
function are very desirable feature of Perl.
Regards,
Frank

The actual problem is that a packed script actually runs inside
a BEGIN block. If you simply put everything in your example script
(except the "use" statements) into a BEGIN block, then it
will blow up even unpacked.
The perlfork man page explicitly states that fork (i.e. the
emulation for Windows) might fail when invoked inside BEGIN.
As to why PAR::Packer wraps a packed script into a BEGIN block:
I don't know - it has always been the case (according to the
history in Subversion).
Cheers, Roderich
