Thanks for the confirmation, I'm closing the bug.

Well, this happens only for Tramp connections which have a session
timeout (sudo, doas) and for compilations which run longer than the
timeout (300 sec per default). Perhaps this doesn't happen for the
majority of users.

Best regards, Michael.

I'm using Emacs 28.0.50 (build 1, x86_64-pc-linux-uclibc) of 2020-05-03.

Compilation processes started with #'compile are killed after some time
when default-directory is let-bound to /sudo::/

Example:

emacs -Q

(require 'tramp)
(require 'compile)
(let ((default-directory "/sudo::/")) (compile "sleep 300"))

This started to happen between January 1 and April 30 (most likely
between March 1 and April 15 but I can't be completely sure).  I'm
calling such code regularly; it is used by ebuild-mode package in the
main Gentoo repository.

(compile "sudo ..") works fine.
