error in process filter: Wrong type argument: integerp, nil

[noprompt]

I get this error whenever I type #_. Emacs will lock up and I'll have to type C-g to regain control. This showed up when I moved from 0.6.0 to 0.7.0alpha (package: 20140613.736). My *Messages* buffer contains the following:

error in process filter: cider-stacktrace-cycle-cause: Wrong type argument: integerp, nil
error in process filter: Wrong type argument: integerp, nil

Edit: Fix order of error messages

[noprompt]

Actually, I get this error message all the time not just with #_.

[noprompt]

So this appears to be a problem only with auto-complete-mode enabled AFAICT.

[bbatsov]

I don't use auto-complete, so I cannot help you with that. CIDER has built-in support for company-mode and that's the only completion system that I recommend/use.

[noprompt]

@bbatsov Yeah. I switched over to ac-cider-compliment and the issue went away. I'm going to close this issue since it isn't a necessarily a cider a problem.

[siscia]

I do get the exact same error without autocomplete enabled.
