I see this same problem in Cygwin. Note that the tests passed recently for me when installing this module in Cygwin about 1 month ago. Sometime in the last month something in Cygwin changed, causing this problem. The module itself has not changed in that time period. I completely reinstalled Cygwin from scratch and the problems still occur. Likely this is a bug within Cygwin itself and not this module.

I had the same problem. I could narrow it down to the following Cygwin modules I updated two weeks ago: _autorebase/_autorebase-000214-1.tar.bz2 _update-info-dir/_update-info-dir-01109-1.tar.bz2 binutils/binutils-2.23.1-1.tar.bz2 gamin/gamin-0.1.10-13.tar.bz2 X11/cairo/libcairo2/libcairo2-1.12.14-1.tar.bz2 gamin/libfam0/libfam0-0.1.10-13.tar.bz2 lcms/liblcms1/liblcms1-1.19-3.tar.bz2 llvm/libllvm3.1/libllvm3.1-3.1-3.tar.bz2 ming/libming1/libming1-0.4.4-3.tar.bz2 openssl/libopenssl100/libopenssl100-1.0.1e-2.tar.bz2 GNOME/libxml2/libxml2-2.9.0-2.tar.bz2 openssl/openssl-1.0.1e-2.tar.bz2 openssl/openssl-devel/openssl-devel-1.0.1e-2.tar.bz2 perl/perl-DBI/perl-DBI-1.623-2.tar.bz2 sqlite3/sqlite3-3.7.13-1.tar.bz2 w32api/w32api-headers/w32api-headers-3.0b_svn5591-1.tar.bz2 w32api/w32api-runtime/w32api-runtime-3.0b_svn5591-1.tar.bz2 X.Org/xorg-server/xorg-server-1.13.2-2.tar.bz2 X.Org/xorg-server/xorg-server-common/xorg-server-common-1.13.2-2.tar.bz2 X11/xterm/xterm-291-1.tar.bz2

I notices that test hangs in ok() in t/01_simple.t in parent & childs in random circles. I am sure that problem with flushing buffers of tty in Test::More I described problem here: https://github.com/schwern/test-more/issues/379
  Mon Jun 10 10:34:08 2013 PERLOVER [...] cpan.org - Correspondence added
I researched problem of hanging in tests Hanging occurs in Test::More line 295 (v0.98 of Test::More) sub ok ($;$) { my( $test, $name ) = @_; my $tb = Test::More->builder; return $tb->ok( $test, $name ); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ } This occurs in parent & child in random circle 'for ()' of 01_simple.t or next test file if 01_simple.t randomly passed. There is very strange behavior: A child or parent process stops somewhere between execution of 'ok' and code's body of Test::Builder::ok. I installed in my tests a logging of checkpoints to my own file in Test::More files and i saw that execution of $tb->ok( $test, $name ) occurs but a run stream not entered to Test::Builder::ok. And after this processes are stopped and hanging in Windows as alone processes (parent has PID as 1, and child as PID of parent PID) May be this behavior occurs because Cygwin/Perl doesn't work correctly with shared memory or/and code segments after forking. I saw that address (reference) of Test::Builder::ok is same for both processes. It's ok for Unix. May be they cannot separate a shared memory to not-shared one if variables are changed after forking. But i think this is problem of low-level programming. I cannot trace more deeply this :(

Here my branch with debug checkpoints Somebody will be able to check yourself https://github.com/Perlover/test-more/commits/perlover/logging_points_v0.98 How to reproduce: Install Test::More from above branch Under Cygwin to make for Test::SharedFork distributive: perl Makefile.PL && make test And after there will be log in /tmp/test-more.txt file My last log file is attached here: Best regards

On Test-SharedFork 0.29, I have experienced this issue again.
