bug#8018: emacsclient crashes on 64-bit linux

[Ahmon Dancy]

Emacsclient crashes with a segmentation fault on x86-64 linux.  I
don't recall the exact circumstances under which it occurs [has
something to do with using a TCP connection].  Anyway, I fixed it a
while back but never reported it directly to this mailing list.
