  This is an automatically generated notice of a new failure of the
  NetBSD test suite.

  The newly failing test case is:

      lib/libcurses/t_curses:copywin

  The above test failed in each of the last 3 test runs, and passed in
  at least 27 consecutive runs before that.

  The following commits were made between the last successful test and
  the failed test:

      2019.05.12.02.19.23 blymn src/lib/libcurses/refresh.c,v 1.109
      2019.05.12.02.29.00 blymn src/lib/libcurses/addbytes.c,v 1.50
      2019.05.12.02.37.24 blymn src/tests/lib/libcurses/check_files/wprintw_refresh.chk,v 1.2
