bug#65640: 30.0.50; segfault when building emacs with native-comp

[LemonBreezes]

Okay. So I can reproduce it by native-compiling org.el. But instead of Emacs segfaulting, I get the following error:

Debugger entered--Lisp error: (wrong-type-argument "/home/st/.config/emacs/.local/straight/repos/org/l..." number-or-marker-p "Segmentation fault")

  signal(wrong-type-argument ("/home/st/.config/emacs/.local/straight/repos/org/lisp/org.el" number-or-marker-p "Segmentation fault"))

  comp--native-compile("/home/st/.config/emacs/.local/straight/repos/org/l..." nil nil)

  native-compile("/home/st/.config/emacs/.local/straight/repos/org/l...")

  emacs-lisp-native-compile()

  funcall-interactively(emacs-lisp-native-compile)

  command-execute(emacs-lisp-native-compile record)

  execute-extended-command(nil "emacs-lisp-native-compile" nil)

  funcall-interactively(execute-extended-command nil "emacs-lisp-native-compile" nil)

  command-execute(execute-extended-command)

Also, I have attached the logs from compiling org.el with maximum verbosity. (~80mb uncompressed)

What happens if you compile org-element.el by invoking

emacs-lisp-native-compile?  That is:

  emacs -Q

  C-x C-f lisp/org/org-element.el RET

  M-x emacs-lisp-native-compile RET

Does Emacs crash if you do the above?  If so, run the above under GDB,

and show the backtrace.

Thanks.
