If both appear and are different, can we characterize the elf file as malformed? Does our current tooling produce such files? If it's an abnormality (requires special elf manipulation or whatever), we could avoid bending backward for this case, and tune the tools to the Normal. > [...] > I suppose a distro can ensure that the IDs are always equal.

Let the clients choose which ID they prefer to look up by. - FChE
