    Description

      /mariadb/10.11/sql/sql_base.cc: In function 'bool fill_record(THD*, TABLE*, List<Item>&, List<Item>&, bool, bool)':
      		 
      /mariadb/10.11/sql/sql_base.cc:9041:32: error: 'rfield' may be used uninitialized [-Werror=maybe-uninitialized]
      		 
       9041 |     unwind_stored_field_offsets(fields, rfield);

      This is not a false-positive, rfield may indeed be uninitialized before use.
