I've tried to trigger this error, but I cannot. Calling "M-x compile",
and invoking "gcc test.cpp" then, returns immediately with one error
message:

--8<---------------cut here---------------start------------->8---
-*- mode: compilation; default-directory: "/ssh:detlef:/home/albinus/tmp/" -*-

What does it need to hang Emacs/Tramp, compiling this file?
