--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I guess the more interesting are the backtrace frames not shown, why it compiler decided to instantiate it just without (resp. with) -g (or -g3 or whatever you are using) and not the other. Is it some hash table traversal from which it is invoked, or what other reason.
