    Description

      &= changes mem_root->flags, which makes condition always true
      Probably & should be used instead of &=

      mysys/my_alloc.c

        if (mem_root->flags&= ROOT_FLAG_MPROTECT)         <<--
      		 
        {
      		 
          mem_root->block_size= MY_ALIGN(block_size, my_system_page_size);
      		 
          if (pre_alloc)
      		 
            pre_alloc= MY_ALIGN(pre_alloc, my_system_page_size);
      		 
        }
