bug#21474: emacs-25.0.50: compilation error in leim: Args out of

[Rob Browning]

For what it's worth, I see a similar error here in a Debian unstable
sbuild chroot, i.e.:

    ELC      leim/quail/TONEPY.elc
    ELC      leim/quail/ZIRANMA.elc
    ELC      leim/quail/ZOZY.elc
  20000 entries
    ELC      leim/quail/arabic.elc
    ELC      leim/quail/croatian.elc
    ELC      leim/quail/cyril-jis.elc

  In toplevel form:
  leim/ja-dic/ja-dic.el:16979:1:Error: Args out of range: "神事/新字/進 信", 10
  Makefile:272: recipe for target 'leim/ja-dic/ja-dic.elc' failed

I'd be happy to try to diagnose this further, if there's anything you'd
like me to try.  Though it's not easy to trigger.

And I actually I hit this while trying to track down another
intermittent failure (that may or may not also only happen in a chroot),
and which may also cause Emacs 25 to be omitted from the next Debian
stable release if I can't fix it soon:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=842728

I was planning to raise that issue on emacs-devel after I'd tried to
reproduce it myself a bit more.  I haven't yet, but someone else (today)
was just able to reproduce it in a similar environment.

Thanks
