Comment 20 for bug 1668093

Upstream has made no change to the tests since then.
I'd have expected upstream to fail as well, but it seems to not fail.

On latest upstream:
autoreconf -f -i
make -j
mkdir /var/empty
cd regress
$ PATH=`pwd`/..:$PATH:. TEST_SHELL=/bin/sh sh `pwd`

Works !

I was able to track down further to a segfault in the bad case.
And in fact it seems to be related to a comment being in the hosts file:
Testable as easy as this:

 $ printf '#foo' > kh.test; ../ssh-keygen -qf ./kh.test -H

All else seem to be follow on issues.

I'll track down the segfault after lunch
