This time I print line number in debug info:
root@54631e34cc9c:~/dropbear-2013.60# ./dropbear -F -E -B [8131] Jun 02 14:07:21 Not backgrounding [8132] Jun 02 14:07:22 Child connection from 172.17.0.2:33726 [8132] Jun 02 14:07:23 Password auth succeeded for 'madper' from 172.17.0.2:33726 [8132] Jun 02 14:07:30 Exit (madper): Error writing: Invalid argument line: 89
So HAVE_WRITEV is true in my case.
