Current state of the main branch is not compatible with Emacs-26.

Loading /home/ubuntu/src/org-mode/lisp/org-compat.el (source)...
Eager macro-expansion failure: (wrong-number-of-arguments (2 . 2) 6)

It is again `setq-local' call with multiple variables. See the attached 
patch that splits it into several parts.
