How so?  I don't see how this could happen.  If the symlink was found
in PATH to run the program, it should be there when the program looks
for it, except in the case where it was deleted or renamed in the mean
time.

                                     or some other method, or because the

Yes, that can happen, but I think that is an error on the caller's
part.  Anyway, there is no other portable method besides argv[0].  I
don't know whether we want to assume that all kernels for GNU will
support /proc/self.
