I think the problem is that load_pdmp doesn't look in libexecdir for a
.pdmp file whose name matches the name of the emacs executable. For
example, suppose I have a symlink /usr/bin/emacs that resolves to
/usr/bin/emacs-nox.exe. Then load_pdmp looks for
/usr/bin/emacs-nox.pdmp, but it doesn't look for
/usr/libexec/emacs/28.0.90/x86_64-pc-cygwin/emacs-nox.pdmp.

Note that in Emacs 29 it uses the fingerprint in the pdmp name,
so that issue should not occur.

Thanks!  I missed that.
