Package: Emacs
Version: 27.0.50


If you try

    M-: (funcall (lambda (x) (= x x)) (expt 2 64)) RET

you'll unsurprisingly get t as result.  Yay!  But if you try

    M-: (funcall (byte-compile '(lambda (x) (= x x))) (expt 2 64)) RET

you should be prompted with an error stating that this largish number is
not a number-or-marker.  This error occurs for example when loading
elpa/packages/xelb/xcb-types.elc.
