 opening .tex file
Date: Sun, 22 Mar 2020 21:10:39 +0100

Hi,

I've been trying out the native-comp branch.

With emacs -Q, opening any file test.tex gives the following error: File 
mode specification error: (error List nesting exceeds 'max-lisp-eval-depth).

Hi Sébastien,

I've recently incurred the same.  Evaluating tex-mode.el solves the
issue therefore I assume the trouble has to be investigate in that file.

Thanks for reporting, it's good we have it listed here.

I looked into it and reduced the bug.

The following code

#+BEGIN_SRC elisp

(defun foo ()
  (message "AAA"))

(defalias 'bar (symbol-function 'foo))

(defun foo ()
  (message "BBB"))

(bar)

#+END_SRC

when compiled by the native compiler prints "BBB" that is clearly
totally wrong.  Actually after loading it any following evaluation of
(bar) prints "BBB".

Interesting we can have two functions with the same name, haven't
thought it... small details :) :)

Going to fix it by the weekend.

  Andrea

I believe this is fixed by d5f6dc131b
"Prevent collisions in C namespace and function shadowing".

BTW also 6075a7c5 removes the trick within latex-mode.el that highlighted
the compiler bug.
