ahAA! We've got a Heisenbug! I was thinking about this discussion after you mentioned you were running v5.18.1 and I was running v5.16.3. The failing tests depend on the order of elements in an array filled by keys. I installed perlbrew and perl-5.18.1 and failed a different set of tests.

The interesting thing is that with a perlbrew installed perl-5.16.3 (to prove that the failed tests were truly caused by the hash randomization feature introduced in v5.18), it still fails 2 tests and yet passes all tests on my fedora 19 packaged Perl 5.16.3 - wonders never cease.

In spite of it waking me up in the middle of the night, I feel quite pleased tracking that down. Think I'll treat myself to a lemon tart in the coffee shop while I re-think the test :)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
