I just can't see p5p adopting this patch simply on the basis of the testing that I've done

The good news is that there has been some more testing done.
Karl Williamson and Jim Keenan created smoke-me branches to specifically test my changes (at http://perl.develop-help.com/?b=smoke-me%2Fkhw-sisyphus and http://perl.develop-help.com/?b=smoke-me%2Fjkeenan%2Fsisyphus%2F41202-2nd-text-float respectively). Many thanks to Karl and Jim for doing that.

The bad news is that the results aren't great. The one smoker (Carlos Guevara's) that has tested those branches has frequently encountered lib/locale.t test failures.
It has also encountered other problems, such as ticket #133356 and ticket #133377, but they are separate issues not related to my changes - and I've no need to concern myself with them for now.

OTOH, the lib/locale.t failures seems to have arisen from the changes I've made, and that's the issue I need to address.
Unfortunately, I can't reproduce those failures locally - and I'm hoping that someone here might be able to help out.

The source for Karl Williamson's branch is here. I would love to enter into a dialog with anyone who can download that file, unpack it, and build from it (on a Unix-type system) a perl that fails any lib/locale.t tests. (I have questions regarding the %Config and locale settings for such a perl).
Having unpacked the source, cd to the top level folder and run: 
sh Configure -des -Dusedevel -Duse64bitall && make && make test

[download]
Examining the individual reports for Karl's branch, I can see that the lib/locale.t failures that I'm interested in are occurring on all of Carlos's FreeBSD and NetBSD systems (but not his OpenBSD system), on his Solaris system, on his slackware system, on his Fedora systems, and on his Ubuntu-14.04 (but not 16.04 or 18.04) system.

I have 2 things to say to anyone who can help me out with this:
1) thank you ever so much;
2) get a life ;-)

Cheers,
Rob
