Gentlemen, both
$ emacs -Q -eval '(compile "locale -m")'
$ emacs -Q -nw -eval '(compile "locale -m")'
work, however the former has lots of "gzip: stdout: Broken pipe",
the latter doesn't.
$ emacs -Q -eval '(compile "strace locale -m")'
shows it happens around
clone(child_stack=0, flags=...
In GNU Emacs 23.1.50.1 (i486-pc-linux-gnu, GTK+ Version 2.18.3)
of 2009-11-29 on elegiac, modified by Debian
(emacs-snapshot package, version 1:20091128-1)
I notice emacs 23.1.1 is also affected.

A simpler test case:
1. emacs -Q
2. M-! locale -m RET
Fails for Emacs 23, but not for Emacs 22 or Emacs 23 run with -nw.

I can't reproduce this anymore, so presumably this old bug is fixed.
Juri, could you confirm?

I still can reproduce this bug on the newest Ubuntu version 10.10 and
GNU Emacs 24.0.50.1 (x86_64-pc-linux-gnu, GTK+ Version 2.22.0) of 2010-10-22

Your shell ignores SIGPIPE for interactive sessions. Gzip checks if SIGPIPE
is ignored, and if it is not, installs a signal handler that prints "gzip:
stdout: Broken pipe". Try
M-! bash -i -c 'locale -m' RET
That gives some job and terminal control errors from the shell, but no gzip
messages. I don't know if ignoring SIGPIPE for subprocesses is the right
thing for Emacs to do.

Since `M-x shell RET locale -m RET' doesn't display broken pipe errors,
then perhaps `shell-command' should do the same and ignore SIGPIPE,
because the output of `shell-command' and `shell' is expected to be the same.

No it doesn't. The error only happens because gzip gets EPIPE while
writing to stdout, which can only happen when SIGPIPE is ignored, which
in fact Emacs does. It's the fault of libgtk.

It isn't.
