When testing the latest bleadperl I'm seeing segfaults

Define 'the latest'. The snapshot or a later (rsynced?) version?

If a later one, please re-rsync. The PMOP patch wasn't apparently
quite right, I took it out for further investigation.

It was an rsync through patch 9053

I've since rsync'ed agian
with patch 9059 and rebuilt with
  All tests successful.

Please accept my thanks for backing
out the problems, and mark this
bug resolved.
