When I try to call latex on any document I get "Wrong type argument:
number-or-marker-p, nil".

Could you please `M-x toggle-debug-on-error RET' and do the same again?
That should pop up a *Backtrace* buffer when the error happens again
whose contents will help debug and fix the problem.

Hello Tassilo,

Here's my *Backtrace*:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  TeX-active-master-with-quotes(t t nil t)
  apply(TeX-active-master-with-quotes (t t nil t))

  TeX-command-master(nil)
  funcall-interactively(TeX-command-master nil)
  call-interactively(TeX-command-master nil nil)
  command-execute(TeX-command-master)

Is it ok like that? Or should I have sent it in a different way?

Thanks,
Uwe

Hm, I can't reproduce it.  AFAICS, `TeX-active-master-with-quotes' can
only signal that error if `TeX-expand-pos' in

      (setq TeX-expand-pos
          (+ TeX-expand-pos (length res)))

is nil.  `TeX-expand-pos' is new in auctex 13.0.0, before an undeclared
variable `pos' was used here.

Do you have some custom code (like a custom entry in `TeX-expand-list')
still using `pos' rather than `TeX-expand-pos'?  If so, have a look at
(info "(auctex) Changes") which tells which breaking changes have been
made in AUCTeX 13.0.0 and how to adapt to them.

Bye,
Tassilo

I still can't reproduce the issue with my testuser account using emacs
27.1, auctex-13.0.0 or 13.0.1, your .emacs (with the windows-specific
parts removed), the above 4 lines in ~/.emacs.d/site-start.el, and your
testdoc.tex.

Does `M-x list-load-path-shadows RET' list something?  (Maybe there's a
leftover from an old auctex install.)

Otherwise, are you able to operate edebug?  If so, please `edebug-defun'
`TeX-active-master-with-quotes', and tell me which expression signals
the error.  If it's really

        (setq TeX-expand-pos
              (+ TeX-expand-pos (length res)))

as I suspected, then you'd probably need to edebug `TeX-command-expand'
to see why `TeX-expand-pos' stays nil rather than being set to an
integer.

Dear Tassilo,

edebug is something that I never used before. But I'm reading the docs 
and if I manage to get something out of it, I'll let you know.

This is what I can report so far:

- `M-x list-load-path-shadows RET' does not list any paths

- I've tried with Emacs 27.1 in its "virgin" state by making my .emacs 
completely empty and by just having nothing but the four lines to load 
AUCTeX in my site-start.el ... the error remains.  

Best,
Uwe

Hi Tassilo,

Good news! With 13.0.1 the error is gone.

Many thanks for your readiness to help!

It's not too hard.  Here's a minimal recipe.

  1. C-h f TeX-active-master-with-quotes RET

  2. Hit RET on the file name link to go to where that function is
     defined.

  3. Set point somewhere on the function, e.g., its name and do
     M-x edebug-defun RET.

  4. Now execute the command triggering the error.  A window will pop up
     showing the file where the edebugged function is defined, and point
     is always before the sexp being evaluated next.

  5. By pressing `n' you can evaluate the current sexp, the result will
     be printed, and evaluation (and point) moves to the next sexp.  So
     just keep on pressing `n' until you get the error and report back
     where it broke.

Thereafte, set point after the function and do C-x C-e.  That will
remove the debugging instrumentation so that you won't pause and be put
into the edebugger whenever that function is called.

Hm, too bad.  That would have been a problem easy to fix.

Argh, so probably something windows-specific.

Oh, well, that was unexpected.  The only change in 13.0.1 compared with
13.0.0 was a fix in how we call the evince viewer with filenames
containing question marks, and that we use spaces instead of tabs for
indenting the code.  Both should have zero effects on your issue.

The only thing I can imagine is that the upgrade deleted some leftover
of some previous 12.x.y install which caused the malfunction.  However,
that should have appeared in `M-x list-load-path-shadows RET'.

Anyway, I'm closing the bug.  Feel free to report a new one in case the
error happens again.

You're welcome!
