You mean, bug#45433?  If the problem is EOL conversion, using
utf-8-unix instead of utf-8 should take care of that.  Or maybe even
use utf-8-emacs-unix.

Are we likely to write bytecode into this temporary file?

Thanks.

To the release branch, if Lars agrees.  But let's first try to see if
bug#45433 is not back after the above change.
