--- Comment #26 from Jakub Jelinek <jakub at gcc dot gnu.org> --- libbacktrace doesn't use malloc (unless mmap isn't supported), handles inline frames just fine and Ian has posted today a patch to support also data symbol lookups. I think I'll post a sanitizer_symbolizer_posix_libcdep.cc alternative on Monday that will use libbacktrace, then users can at least choose what they prefer, say at configure time.
