Using ac-slime I am getting the following errors: Error running timer ‘ac-update-greedy’: (wrong-type-argument number-or-marker-p \.\.\.) [3 times] Error running timer ‘ac-show-menu’: (wrong-type-argument number-or-marker-p \.\.\.)

I re-installed all auto-complete components from Melpa because this was mentioned as solution in similar cases, without a change.

I filed an Issue but the original author of ac-slime is not using auto-complete any more. I tried to find something in the source which could cause this but my elisp knowledge is just too limited. As far as I can see, there was no change in auto-complete for years, so I have no idea why this happens and how it could be solved.

Is anyone using ac-slime or should I switch to company?

I found the cause for this issue: Somehow my ac-comphist.dat was corrupted and therefore led to this error for some candidates. I cleared the file and everything works fine again.
