I'm currently on 17ecfa8698 and get that problem also on another
computer (but with the same ~/.emacs).

Yes, I also made a full "make bootstrap" to be sure but the error
persists.

I cannot reproduce the issue with "emacs -Q", though, so it's most
probably something with my configuration or some 3rd party package.  If
I'd know the function call site or at least what function's called with
too many args, I'd probably figure out what's the problem.

I've tried:

--8<---------------cut here---------------start------------->8---
❯ gdb lib-src/emacsclient
GNU gdb (GDB) 9.2

Any help?  My GDB foo is quite low but I can operate it when given
instructions.

Bye,
Tassilo
