Hm... this doesn't crash Emacs on this Linux machine, at least.

This is happening in the code paths that were refactored during the
async network rewrite, but this seems to be called pretty
straightforwardly here (not in a callback from the DNS code). (Which
makes sense, since Windows doesn't have getaddrinfo_a...)
Hm... coding=0xffffffff looks pretty suspicious, but it's difficult to
tell with an optimised build.
