GCC 13 -Wdangling-pointer in execute_show_status()

Details

    Description

      GCC 13 emits a new warning for some old code from 2006:

      10.4 9c0e91a27cc58d1b5076435e125c70cd277fd989

      		 
      /mariadb/10.4/sql/sql_parse.cc: In function 'bool execute_show_status(THD*, TABLE_LIST*)':
      		 
      /mariadb/10.4/sql/sql_parse.cc:6506:26: error: storing the address of local variable 'old_status_var' in '*thd.THD::initial_status_var' [-Werror=dangling-pointer=]
      		 
       6506 |   thd->initial_status_var= &old_status_var;

      Possibly this could be fixed by allocating old_status_var from the heap. I don’t think that alloca() would help here.
