Hi,

addr2line.c:457 has:
      char *name = NULL;
      if (sscanf (string, "(%m[^)])%" PRIiMAX "%n", &name, &addr, &i) == 2
          && string[i] == '\0')
        parsed = adjust_to_section (name, &addr, dwfl);
      switch (sscanf (string, "%m[^-+]%n%" PRIiMAX "%n", &name, &i, &addr, &j))

And in the portability branch that got changed to:
      char *name = NULL;
      if (sscanf (string, "(%a[^)])%" PRIiMAX "%n", &name, &addr, &i) == 2
          && string[i] == '\0')
        parsed = adjust_to_section (name, &addr, dwfl);
      switch (sscanf (string, "%a[^-+]%n%" PRIiMAX "%n", &name, &i, &addr, &j))

But I think that that doesn't make sense.  Isn't %m the gnu extention,
and that %a now follows the C99 standard and expects a float *?
