I couldn't get the code to run either, but this sounds like several
other exec-not-flushing-STDOUT bugs that were fixed a while ago but only
closed recently. OP, if you are still around, are you still seeing this
issue with newer versions of Perl?

Since this ticket has been silent for over a decade, I recommend leaving
it open for thirty more days, then closing it unless we get new
information or other complains.
