record (for example in ma_test_loghandler-t). Reason was
wrongly matched () in DBUG.


storage/maria/ma_loghandler.c:
  Wrongly matched parenthesis:
  DBUG_PRINT(keyword, argslist) expands to roughly
  _db_doprnt arglist;
  So DBUG_PRINT("enter",(a);
  b;
  c);
  expands to roughly
  _db_doprnt(a);b;c;
  which is valid code. Except that in non-debug builds, DBUG_PRINT(
  expands to nothing so the wrongly "included" code is thrown away,
  leading to some members of "scanner" to not be initialized.
