Look at their time stamps, and compare with that of the Emacs
executable.

Also, I don't understand why you see the .1, .2, .3, etc. suffixes
there: they aren't supposed to be in the installed directories.

Yes, if Emacs finds a .pdmp file right next to its executable, it
tries to use it.

> I believe, during the make install, somehow the Emacs.pdmp gets copied into the libexec directory, but an invalid Emacs.pdmp stays in the parent directory of libexec.

Yes, and that invalid (old) file should be removed by hand.
