build failure in master: zero-length memset

[Julian Graham]

Hi all,

I'm getting a build failure on master caused by a warning about a
zero-length call to memset (which reminded me of  what Ken and Ludo
were talking about here [1]).

  /usr/include/bits/string3.h:82: error: call to
‘__warn_memset_zero_len’ declared with attribute warning: memset used
with constant zero length parameter; this could be due to transposed
parameters

Haven't had a chance to debug it at all, but in case it's handy, `gcc
--version` gives me: "gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3"


Regards,
Julian
