bug#23053: 25.0.92; error in cc-mode when editing C# file with a generic class inheritance

[Saulius Menkevičius]

Hi,

Not sure why I did not receive and email directly from debbugs.gnu.org
(maybe there is some delay in mail transfer mechanism on the way).

The mode in question is csharp-mode, from MELPA:

    csharp-mode is a dependency package.

        Status: Installed in ‘csharp-mode-20160217.1211/’ (unsigned).
        Version: 20160217.1211
        Summary: C# mode derived mode
    Homepage: https://github.com/josteink/csharp-mode
    Keywords: c# languages oop mode 
    Other versions: 20160217.1211 (melpa-stable), 0.8.12 (marmelade).

Not sure if you've checked the tracked for this issue, but Jostein

    I've run this test-case against the "regular" Windows build 24.5.1,
    using latest csharp-mode package and it runs fine. Trying latest Emacs
    from git master on Ubuntu I can reproduce this error systematically
    using the exact same version of csharp-mode.

So this is can be replicated with bare emacs-25 from git + csharp-mode from
MELPA. Also someone wrote that the same thing happens with Java mode too
where the code being edited uses generics (as C# and Java generics syntax is
very similar).

Oh, it was my first time using `report-emacs-bug', -- I invoked
it from my mail client buffer instead of from the csharp-mode that has
issue itself.

Thanks!
