Thanks for the report. You are hit by an infloop, due to some code
reorganization in Tramp. Fixed in master.

Hmm. According to the backtrace, Tramp has sent "/usr/bin/test -e / 2>/dev/null"
to the sudo process. It didn't return; you seem to have interrupted this
(it signals `quit').

What happens if you apply "/usr/bin/test -e /" in a sudo shell? And
could you, pls, send next time the debug buffer
*debug tramp/sudo root <at> fgunbin.local* instead just the backtrace?

sh: /usr/bin/test: No such file or directory

Attached debug buffer.

That's OK.

Thanks. It is the famous "echo -n" bug; this command isn't
portable. I've fixed this on master.
