From @khwilliamson

This is a bug report for perl from khw@​cpan.org,
generated with the help of perlbug 1.39 running under perl 5.15.8.

---

A "Use of uninitialized value in split" message is emitted under very
limited circumstances with charnames​:
  1) appropriate warning category must be on
  2) Must be in the scope of a 'use charnames ()'; i.e., no import
  3) Must be one of the four code points that had no official Unicode
  name prior to release 6.1. Namely 0x80, 0x81, 0x84, and 0x99.

I see these patches, which I thought we were going to apply​:

* [7711871] (p5p/smoke-me/khw-charnames) charnames​: White-space only
* [af6342a] PATCH​: [perl #11560] extraneous msg in viacode

They were not applied. Karl, do you think we should squash this before 5.16? Fewer warnings​:
good. If you think it's good too, and safe, I will cherry pick these.

Thanks.

I didn't see any approval to apply them.

It's a minor bug, but I'm confident it's safe.

Turns out it wasn't safe! cmp_versions test failed. :-)

I bumped _charnames.pm's $VERSION and pushed it up to blead.
