Many (but not all) of B::Utils "parent" tests fail on OpenBSD 3.9, both perl 5.10.0 and perl 5.10.1 (multithreaded build). I've attached the output of $ make TEST_FILES=t/utils/30parent.t TEST_VERBOSE=1 test I've tried building B::Utils 0.06, 0.07, and 0.08 with the same results. $ uname -a; perl -v OpenBSD pinky.yary.ack.org 3.9 GENERIC#617 i386 This is perl, v5.10.1 (*) built for OpenBSD.i386-openbsd-thread-multi

The same problem still appears on OpenBSD 4.7 under Perl 5.12.2 non-threaded, in 0.11

This is pretty consistently failing for NetBSD and OpenBSD. I've requested shell accounts from some hosting providers. I'll fix this if I get access to a machine that will reproduce this failure. As is, I'm just in the dark about what's going on.

I cna provide a shell account on an Open BSD host that is failing. Have to warn you that the OS is about 5 yrs old and git is broken on there! But it will let you see what is happening. Give me contact info and a desired userid. -y ~~~~~ The Moon is Waning Gibbous (70% of Full)

If anyone from OpenBSD-land is interested in fixing this, I can certainly hand some PAUSE upload privileges to you. On Sun, Mar 11, 2012 at 8:04 AM, Zak B. Elep via RT <bug-B-Utils@rt.cpan.org> wrote: Show quoted text

Maybe you should apply https://github.com/jbenjore/B-Utils/pull/9 pull request ? It appears this issue is reproducible for me on demand using a linux's perbrewed 5.26 with the "perl -V" output appended at this end of this email. You may reproduce it locally by installing perl as I did, i.e.: perlbrew install perl-5.26 -DEBUGGING=both -Dusethreads The B::Concise output (obtained by uncommenting lines at the top of t/utils/30parent.t - glad you wrote those lines!) is showing that the issue is very probably related to negative numbers when searching for parent: main::test_data: 1q leavesub-UNOP=(0x80616c58) K/REFC,1 ->(end) - lineseq-LISTOP=(0x805f9078) KP ->1q 1 nextstate-COP=(0x805f909c) (main -5690 30parent.t:10) v ->2 -
