tramp-sh.el sets HISTFILE=/dev/null, which cause the file to be deleted when /bin/bash is the default /bin/sh (which is the case in Arch). For details, see:

Patch which uses HIST{,FILE}SIZE instead, as done in newer versions of tramp-sh.el:

Steps to reproduce:

M-x /root@localhost:<somefile>

Edit until HISTFILESIZE is exceeded, notice /dev/null is replaced by a regular file.

Do you use the tramp version bundled with Emacs?

This seems to be already fixed in recent tramp releases:

Yep, I use the tramp version bundled with emacs 24.5-2.

It's fixed in emacs 25, but I'd say it's an important enough issue to backport it to the Arch package.

I prefer not to include single patches for Elisp-packages.

The correct way is to install a recent tramp release using the emacs packages manager.
There are a lot of bugs fixed since the emacs-24.5 release.

I also checked the Fedora-Package. They also don't include this patch.
