It gets the correct result if the entire file content is passed to the update method in one big hunk. I guess I'll go through the code and compare it to whirlpool.c from the reference implementation (assuming it gets the same result as openssl): http://www.larc.usp.br/~pbarreto/whirlpool.zip
This is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=3596fc3822bb82dfe05a58fdb78220e399175a4d
This is in 2.2.0_alpha91, but I'll leave this bug open until it's in an unmasked release.
This is fixed in 2.1.10.50.
