Hmm. What system is this on? What errno code corresponds to
"Bad file descriptor"?

This is coming from

thisfd = dup(0);
if (thisfd < 0)
{
/* Expect EMFILE or ENFILE, else it's fishy */
if (errno != EMFILE && errno != ENFILE)
elog(WARNING, "dup(0) failed after %d successes: %m", used);
break;
}

I would suppose there is another EXXX code we have to allow to pass
without comment, but I don't know from your report what it is.
