I had forgotten to delete an already disabled line of C++ code.

sql/sql_insert.cc:
  I had forgotten to delete this line (it was already disabled using //;
  this line was not needed because we do the empty() every time
  we write to the binlog (in MYSQL_LOG::write());
  t/binlog_stm_binlog.test already tests that the empty() indeed happens
  for INSERT DELAYED.
