This works:

$ emacs -Q -batch -eval '(let ((default-directory "/")) (with-temp-buffer (process-file "hello" nil (list t "/tmp/stderr")) (princ (buffer-string))))'
Hello, world!

This works, too:

$ emacs -Q -batch -eval '(let ((default-directory "/ssh:localhost:/")) (with-temp-buffer (process-file "hello" nil (list t "/tmp/stderr")) (princ (buffer-string))))'
Tramp: Sending command ‘exec ssh -e none localhost’
Tramp: Found remote shell prompt on ‘localhost’
Hello, world!

But with SSHFS, it doesn't work:

$ emacs -Q -batch -eval '(let ((default-directory "/sshfs:localhost:/")) (with-temp-buffer (process-file "hello" nil (list t "/tmp/stderr")) (princ (buffer-string))))'

The output buffer stays empty.
The same behavior can be observed on the master branch.

I've fixed this, pushed to the master branch. Will also be available
with next Tramp 2.5.2.2 in GNU ELPA.

Closing the bug.

Best regards, Michael.

PS: The command as given by you in the example will write stderr to the
file "/tmp/stderr", and not to "/sshfs:localhost:/tmp/stderr" as you
might expect. No difference in the given example, but you might be
surprised if you use another target but "localhost".

Best regards, Michael.

I'm aware, but thanks for the reminder!
