    Fix for bug #21476: stack overflow crashes server; error-message stack reservation too
small
      - due to the failing execution_constants test on the hpita2, 
        increase STACK_BUFF_ALLOC, that is used in the Item_func::fix_fields() to 
        allocate on the stack a "dummy" buffer large enough for the corresponding exec.
