bug#35180: 27.0.50; emacs daemon and “package” often inserts [I when opening file

[Han Boetes]

Digging further and stripping out more unnecessary options that are not required to reproduce this issue: I got down to this:

cd

mv ~/.emacs.d{,.orig}

mkdir .emacs.d

touch .emacs.d/init.el

xrdb -remove

xrdb -query # Just to prove there are no Xresources active

pkill emacs; sleep 1; /usr/local/bin/emacs –no-init-file –no-site-file –no-splash –daemon; emacsclient -t .emacs.d/init.el

[I

This happens about 25% of the time. But if I replace “–no-init-file –no-site-file –no-splash”

 with “-Q” it no longer happens. It seems there is an undocumented difference here.

I straced it and this is what I got: Check the write() line, see also the attachment for the complete strace file.
