Subject: 26.0.91; Error in Edebug when debugging inline-letevals
Date: Tue, 03 Apr 2018 11:47:18 -0700

Using Edebug on code containing inline-letevals produces an error.

To reproduce, enter the following code into *scratch*:

;;;  -*- lexical-binding: t -*-

(defvar my-count 0)
(defun my-number ()
  (setq my-count (1+ my-count))
  (message "my-count is %s" my-count)
  my-count)

(define-inline my-divisible-p (n)
  (inline-letevals (n)
    (inline-quote (or (eq 0 (% ,n 2)) (eq 0 (% ,n 3))))))

(defun my-func ()
  (message "the result is %s" (my-divisible-p (my-number))))

(my-func)


Then:

M-x edebug-all-defs RET
M-x eval-buffer RET
g g

Result: Args out of range: [20 48 59 70 71 72], 7

Instrumenting lisp/net/shr.el with Edebug produces a "Wrong type
argument consp, nil" error at the use of shr-char-kinsoku-bol-p which
also uses inline-letevals.
