++Subject: 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.
++
++Origin: upstream, commit: aad38d6010d9eef07685fa52ce93bcf70512f88b
++Bug: https://bugs.gnu.org/57562
