You are probably right, because I see the same failure on GNU/Linux,
in an x86_64 unoptimized build:

  Test module/function-finalizer condition:
      (ert-test-failed
       ((should
	 (equal
	  (mod-test-function-finalizer-calls)
	  expected-calls))
	:form
	(equal
	 (0 0)
	 (1 0))
	:value nil :explanation
	(list-elt 0
		  (different-atoms
		   (0 "#x0" "?")
		   (1 "#x1" "?")))))
     FAILED  26/27  module/function-finalizer (0.247565 sec)
