I tried this recipe in Emacs 24.5, and I got the same backtrace as you:

> %%% Backtrace
> Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p
> noindent)
>   smie-indent--rule(:after "{" 242 nil 239)
>   smie-indent-after-keyword()
>   run-hook-with-args-until-success(smie-indent-after-keyword)

But on the trunk, I just get a message saying "Nothing to change", so it
looks like this has been fixed by now, and I'm closing this bug report.
If you're still seeing this in Emacs 27, please reopen.
