Running into it from ert-tests which call ‘jit-lock-fontify-now’
When reproduced from emacs -Q in scratch-buffer:
Debugger entered--Lisp error: (wrong-number-of-arguments (2 . 2) 0)
jit-lock--run-functions()
eval((jit-lock--run-functions) nil)
elisp--eval-last-sexp(nil)
eval-last-sexp(nil)
funcall-interactively(eval-last-sexp nil)
call-interactively(eval-last-sexp nil nil)
command-execute(eval-last-sexp)
AFAIU caused by
jit-lock--run-functions from jit-lock.el, line 378, last line below
(setq loose-beg (min loose-beg this-beg))
(setq loose-end (max loose-end this-end))
nil)))
`(,(min tight-beg beg) ,(max tight-end end) ,loose-beg ,loose-end)))
‘min’ fails as ‘tight-beg’ is still nil, not updated from setq inside
pcase above.
