--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue goes away when using -fno-ipa-icf - we have

# 2 "/usr/include/sys/unistd.h" 2 3 4
# 9 "getgid.c" 2
# 14 "getgid.c"
gid_t _POSIX_types_Gid =3D 0;
gid_t
getgid (void)
{
  return _POSIX_types_Gid;
}

gid_t
getegid (void)
{
  return _POSIX_types_Gid;
}

which we first ICF and then inline back.  So it looks like when "materializ=
ing"
the alias clone for getegid we get a wrong location (or the location for the
alias clone is broken / not initialized?)
