Oh, clang pointed out a very similar issue with wc:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=0eaa993a
We'll amend your patch as per above I think?

Unfortunately du didn't do anything that clang noticed as suspicious,
but I should have grepped for AI_ERR_READ to show that wc and du
are the only utils to check it.

cheers,
