I have now run ltrace a half dozen times and the problem does not recur.
The test cycle is about 20 minutes, so I don't have time to test it
too many ways.  So, it seems, ltrace itself interferes with reproducing
the problem. (The problem recurs when running without ltrace.)
To emphasize:  this problem goes away by itself sometimes.  Once it
does go away, it stays away until I reboot.

Here is an ltrace for a successful run:

$ cat tst/dprintf-posix2-1.ltrace
