log REFACTOR create EMEM messages w/o problems with freeing error structures
Message in ly_err_item is supposed to be dynamically allocated and it is
freed when freeing the structure. But in case we face memory allocation
failures, it is necessary to try to create the structure with a simple
static string without issues with freeing the structure.
