Firstly I thought Quarry somehow managed to misinterpret GNU Go's
responses, but:

address@hidden quarry]$ ~/gnugo/interface/gnugo --mode gtp -l ~/heikki.sgf
genmove black
= resign

Seems like `resigning.html' should be revised.  If this behaviour seems
undesirable, we should also revise GNU Go itself.

In `genmove.c', function should_resign():

  /* We resign 19x19 games only, smaller board games are fast enough.
   * We resign only if the margin is bigger than 45 pts and if we are
   * behind (of course).
   *
   * As an exception to this rule, we resign on any board size if
   * it looks like all our dragons are dead and the generated move
   * is a pass.
   */
  if (move == PASS_MOVE && !lively_dragon_exists(color))
    return 1;
