error "Marker does not point anywhere"

[dakling]

Hi,

I just got started with haskell-mode and am facing a weird issue: whenever I run haskell-process-load-file on a file that contains an error, any subsequent runs of this function result in error "Marker does not point anywhere". The full stacktrace reads

Debugger entered--Lisp error: (error "Marker does not point anywhere")
  goto-char(#<marker in no buffer>)
  haskell-interactive-mode-goto-end-point()
  (save-current-buffer (set-buffer (haskell-session-interactive-buffer session)) (haskell-interactive-mode-goto-end-point) (let ((mrk (point-marker))) (haskell-session-set session 'next-error-locus nil) (haskell-session-set session 'next-error-region (cons mrk (copy-marker mrk t)))) (goto-char (point-max)))
  haskell-interactive-mode-reset-error(((name .

"") (command-queue) (inferior-process . #<process dnschannel>) (is-restarting) (current-command) (suggested-imported) (sent-stdin) (evaluating) (session . #1))))
  haskell-process-load-file()
  my/haskell-load-and-run()
  funcall-interactively(my/haskell-load-and-run)
  command-execute(my/haskell-load-and-run)

Annoyingly, this error also occurs when I try to restart the haskell process or close the corresponding buffer, forcing me to quit emacs altogether.

I found this old issue describing a similar problem, but I am not sure if this is related, because 1) this issue seems to be fixed now and 2) my path does not contain any spaces.

My emacs version is 29.1.

Any ideas what is going on here?
