csharp-mode from Melpa: Invalid search bound (wrong side of point)

[Steinar Bang <sb@dod.no>]

Platform: Win7 x64
          GNU Emacs 24.4.1 (i686-pc-mingw32) of 2014-10-24 on LEG570
          csharp-mode 20150514.251 (from Melpa)

I've pulled in csharp-mode from Melpa, and when I do 'M-x occur' in a
buffer in csharp-mode I get the error message: Invalid search bound (wrong side of point)

See also the error stack trace below.

Has anyone else seen something similar, and/or know what might be
causing it, and might have an idea how to fix it in csharp-mode or find
a workaround?

Thanks!
