> Additional note: I just found the 0.73_01 release, which seems to fix this problem. (Thank you!)
Thanks for the report. This is a known bug but it is assumed to be a bug in Perl's threading, not Test::More. Furthermore, it is a heisenbug. Sometimes it appears, sometimes it does not. 0.73_01 changed very little, nothing to do with threading, which illustrates the nature of the bug. If you run 0.72 again it will probably pass. In almost all cases this bug appears in vendor patched versions of Perl. Previously it was confined to Redhat derivatives, this is the first example I've seen on OS X. In short, if you don't plan on using threads in your code don't worry about the failure, it won't effect you. I've yet to come up with a good way to communicate this sentiment to the user. -- Insulting our readers is part of our business model. http://somethingpositive.net/sp07122005.shtml

Thanks for the report. This is due to known bugs in Redhat's and other vendor's release of perl. It might also be a general 5.8.5 issue. You can try upgrading to a newer Redhat perl, if one exists, but the best fix is to compile your own clean copy of 5.8.8. -- Ahh email, my old friend.

It turns out a clean 5.8.6 has problems with this test, too. So your best bet is to upgrade to 5.8.8. PS This test is only relevant to you if you write code with threads. -- ROCKS FALL! EVERYONE DIES! http://www.somethingpositive.net/sp05032002.shtml

Subject: t/is_deeply_with_threads...... Failed 455/505 subtests
Using latest RedHat AS4.6 - fresh new install - almost all CPAN modules fail, because they rely on this one, which fails with this:- t/is_deeply_with_threads...... Failed 455/505 subtests

I have decided to turn off the is_deeply_with_threads test. It tickles intermittent threading bugs in certain perls about which I can do nothing. Known vulnerable perls include OS X's 5.8.6 and most Redhat derived vendors.
