Uhm, hold on a second. Is this intended?

No, not at all intended. That bug is now fixed in git and snapshots.
Just for the record, the bug Jack exposed is that when an
autoregressive "genr" expression, such as
y = y(-1) + u
was evaluated in a panel dataset, the resulting series was all
missing values apart from the first individual in the panel. This
was a regression associated with the change in gretl's internal
definition of "NA" or missing that took place in git in August of
this year. But that change was reverted for the 2018c release, since
it hadn't been tested fully enough, so the problem is not present in
gretl 2018c.
