Basically, if a test combined both NA and NaN in the same sum/mean/prod calculation then the result is essentially up in the air as to whether it will be another NA or NaN.
While I was actually trying to test this difference before by using expect_identical(), it isn't really worth the effort since the base equivalents don't make any promises about it either.
The easiest fix is to just switch to expect_equal() where NA_real_ and NaN are considered equivalent.
Closes #198
