#208936 — Buster emacs crashes with doc-view-mode

Hello folks,

In EMACS, I often switch between doc-view and pdf-view to read PDFs.
Occasionally, EMACS crashes with this backtrace:

This is intensely annoying, since I usually have ~100 PDFs open.  Any ideas?

Cheers!

Your backtrace looks quite similar to this:

http://codepad.org/juUbz33Q
https://www.reddit.com/r/emacs/comments/9xrjto/emacs_latex_docview_bug_crashes_emacs/

The OP believes his issue is related to the 'doc-view-resolution'
parameter (when reverting from 300 to a setting of 100 the crash doesn't
seem to occur for him).

Thanks for the pointer -- I have replaced my resolution of 600 (!) to 
150, with a minimal hit (my monitor is 141 dpi) -- I'm not claiming the 
crash stopped, just probably will happen less often.

That said, some searching pulled up Fedora seeing this for a while, and 
this being a standing issue in debian -- anybody familiar with the 
history here?
