Excellent! I get the failure by simply doing a "perl Makefile.PL" and a
"make". My perl was a bit more vocal regarding where the problem is...

I need to build a bleadperl with debugging on the see if this has been
fixed already, which I suspect it has already.

I ran the install against a bleadper, and everything worked just fine.
  Since Perl_preregfree() is completely different with bleadperl than
5.8.8, I'll have to try with a debugging 5.8.8 next to see where the
error is.

Given that the version of Perl referenced in this ticket is no longer
supported, do we need to keep this ticket open?

Thank you very much.

Well, it would be nice to know if we actually fixed the bug, or if the
symptoms just went away. (ie what the cause was)

But the ticket records that there were (at least) no symptoms on then-blead

I can't replicate this (with 5.8.8 on a current machine)

I propose that we keep this RT open for 30 days, then close if we do not
hear from the OP or receive additional complaints.

Thank you very much.
