I am working on Parrot (http://www.parrotcode.org), a
VM that is in development that will be running Perl6
and hopefully many other languages. After upgrading
to the 1.5.11-1 version (from 1.5.10-3) of
cygwin1.dll, I am getting mysterious IO behavior when
doing Parrot threading. Basically it appears that
when a thread finishes the FD is closed and subsequent
prints in a still active thread don't get printed to
I have confirmed the behavior is with the cygwin1.dll
by swapping the two around and re-running the tests.
Unfortunately I am admittedly a novice and have no way
of isolating the problem further. I checked the
change log in the cygwin1.dll announcement and didn't
see anything that stood out other than very
peripherally (audio FD copying).
For anyone willing to trouble shoot the problem, I
will be more than happy to help get Parrot working
(the latest CVS checkout should build out of the box
if you use a system ICU). The following command will
illustrate the problem from the directory where Parrot
$ perl t/harness --gc-debug --running-make-test -b
