JFTR: "echo `ps | cat`" already suffices.

IIRC that happens since one of the 5.0.3 release candidates (i.e.
5.0.2-test-$something), at least since 5.0.3.

Definitely not only on ARM. I do have it on i386 (x86 32 bit) and
amd64 (x86_64), too, also already with procps 3.3.8.

I reported (as more or less requested) against procps-ng in Debian:
http://bugs.debian.org/732410 (and since procps-ng is the "Debian,
Fedora and openSUSE fork of procps" this probably can be considered as
"reported upstream", too. :-)

		Kind regards, Axel
