From 6a1aaa00c94b1516c8c098322af5a591e7c35341 Mon Sep 17 00:00:00 2001 From: Stefan Monnier Date: Sat, 3 Sep 2022 11:03:01 -0400 Subject: [PATCH] Emacs should no longer crash when the eln-cache isn't writable This upstream patch has been incorporated to fix the problem: * lisp/emacs-lisp/comp.el (comp-run-async-workers): Fail more gracefully Otherwise Emacs may fail to start if it can't find a writable `~/.emacs.d/eln-cache` directory. Fixes bug#57562. See also Debian's bug #1017739.
