Stuart,
As a follow-up, the errors are of the '*** caught illegal operation ***' variety which is frequently seen when different compiled components (and particularly C++ ones) are out of sync with respect to their toolchains. So I would suggest a clean rebuild, but given that it is at CRAN that is out of our hands.
