Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.

I use auctex from the Archlinux pacman distribution.  Recently, preview
latex ceased to function.

My .emacs init file consists solely of these two lines:

(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)

(My usual .emacs is about 880 lines long.)

On running any of preview-latex's preview commands, e.g. C-c C-p C-b,
all the maths is prefixed with a red circle with a hoyizontal white line
through the middle.

mouse-2 on such an icon results in the following:

The preview.dsc file does exist, its a postscript file containing the
formatted first equation.  No other files are written to that
_region_.prv directory.

The input file is by no means unique; I get the same behaviour with
every LaTeX file I've tested.

Gnuscript developers have decided to remove the .runandhide operator
(the only available and documented mechanism for entering SAFER mode
temporarily and safely) in Ghostscript 9.22.  I have committed a fix to
AUCTeX master that removes all uses of .runandhide from preview-latex
(preview-latex already had been changed previously to not require
returning from SAFER mode, so this change is not security-relevant).

I haven't heard back from any of the current AUCTeX
developers/maintainers so I have no idea when this fix will actually
make it into a release.

You might want to either apply this recent commit in the AUCTeX
repository to your AUCTeX distribution (it's

commit 837d590008c1dd4e92ffbce15008efb761d11f7c

    Remove use of .runandhide operator
    
    Ghostscript bug 698680
    <https://bugs.ghostscript.com/show_bug.cgi?id=698680> has been caused
    by the removal of the .runandhide operator in Ghostscript 9.22
    upstream.  Since .runandhide has no longer been used in a
    security-critical manner, its operation can be emulated by storing the
    respective information in a .preview-ST variable.  Potentially
    malicious code would not be able to retrieve a non-safe "save" object
    from here.

) or downgrade your Ghostscript to 9.21.

You sent a humongous mail of 12MB size to the AUCTeX bug list: I'll
reject that mail since it adds nothing new.

The way I understood Mosè it will be in the next release.  I'm closing
this ticket since the issue itself was resolved in #28811.
