} I'm thinking that getjob() may need a setcurjob() before it checks curjob.
Since Sven has been incommunicado for a couple of days, I tried to look
into this myself in more detail. The only two places where getjob() is
called are from bin_kill(), and from bin_fg() *after* the setcurjob()
that you noted.
I can believe that a race condition might cause "no such job: 3" once,
but twice in a row is impossible. So the only possible answer is that
the one and only job has STAT_NOPRINT set but *not* STAT_SUBJOB, which
in turn happens only at exec.c:768 and 806 (in 3.0.8; in 3.1.6-dev-19,
exec.c:993 and 1031), both in execpline(). See jobs.c:setprevjob(),
which is called from setcurjob().
Now, it may be that the right solution is to have setprevjob() ignore
jobs that have STAT_NOPRINT set, but I wouldn't want that to mask some
more serious job-state problem. If you have any insights, share 'em.
