--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
BTW, yet another option (and I'd say much more readable) is just using
build_message_string function, so
snprintf (errmsg, err_len, "Rank mismatch in argument '%s' (%i/%i)",
s1->name, symbol_rank (s1), symbol_rank (s2));
would be converted to
*errmsg
= build_message_string ("Rank mismatch in argument '%s' (%i/%i)",
s1->name, symbol_rank (s1), symbol_rank
(s2));
etc.
The caller would need to free it afterwards. Note, the Fortran FE already uses
this function as well.
