No. The Comtet reference, at least, shows that these two definitions are equivalent.

A program being used to generate one definition or the other must have an error of some sort; probably a rounding error, as I suggested.

Dear Seqfans,I mentioned the problem with A046988 in a list exchange with
Robert Israel in early 2016:> (I suppose A046988 has to be revised. The simplest approach would

There can be subtle effects of cancelling in sequences involving
Bernoulli numbers.
