Various test suite failures with perl5.14.2 on multiple platforms

I have tried to install Parse-CPAN-Packages 2.35 on all the following platforms, for all of the following perls: Platforms: 32 and 64 bit RHEL 5, Solaris 10, and AIX 6 Perls: 5.10.1, 5.12.4 and 5.14.2 All of the tests pass for ALL of the 5.10.1 and 5.12.4 combinations. However, SOME of 5.14.2 builds failed with a number of errors that I suspect may very well expose bugs in perl5.14.2, not necessarily this module. However, I can't reproduce them outside of these test suite runs, so I'm reporting it here. I suspect this will end up on the perl bug queue, though. The attached file has the notes I made while debugging this, and as you can see, something's breaking when perl stats the 02packages file, or at least that's what it looks like to me. I can reproduce this easily, so if you would like additional debugging info, just let know.

I haven't had time to repeat this debugging effort, but I see the same symptoms with the 2.37 release. The only difference is that the failures are all for 32-bit platforms. If there's any interest in this, I'll dig deeper, but if not, I won't invest the time (takes quite a while to put that report together) On Thu Nov 17 16:27:48 2011, WPMOORE wrote: Show quoted text

First off, thanks for doing the debug work. My only comment there is: I'm highly suspecting that the debugger is skewing results, and as such an approach of adding print lines to the code itself might make pinpointing the real issue easier and more accurate. As for the last release: It will behave exactly as the previous release. It was only done to fix some packaging issues: https:// metacpan.org/diff/release/MITHALDU/Parse-CPAN-Packages-2.36/MITHALDU/ Parse-CPAN-Packages-2.37 Similarly, the 2.36 release only fixed an issue with the tests and was done to try and get more useful data out of http:// analysis.cpantesters.org/solved?distv=Parse-CPAN-Packages-2.36 As such i don't think there will be no need to repeat the same debugging effort, unless you're willing to try it with debug printing. As to the issue itself: I am very interested in finding the root cause, but find myself with a lack of time to adress this. I will however keep it in the back of my mind.
