Inappropriate error message on saving new file

Inappropriate error message on saving new file

[Frederick Bartlett]

I’m running Emacs 30.0.50 on Fedora 39.

When I save a new buffer, I get the following upon first saving it, even
after checking that the auto-saved file exists:

Debugger entered--Lisp error: (void-function delete-file)
  delete-file("<FILEPATH>#<FILENAME>#")
  delete-auto-save-file-if-necessary(t)
  basic-save-buffer(t)
  save-buffer(1)
  funcall-interactively(save-buffer 1)
  call-interactively(save-buffer nil nil)
  command-execute(save-buffer)

I note that delete-auto-save-file-if-necessary occurs after delete-file;
but I don’t see how that could produce the error message.

After ignoring that first error, everything works as expected, so it’s not
a major problem, but I’d like to understand what Emacs is doing.

Thanks!
Fred

I'm guessing this is not in "emacs -Q", in which case crystal ball
says some of your customizations are responsible for this.
delete-file is a primitive, i.e. implemented in C, and is always
available in Emacs, so the only way to make it disappear is if some
code makes its function cell void.
