This getRegister bug is killing my Windows builds too; indeed every 32-bit build is broken, and that is stalling a lot of people, now including me.
Could you perhaps revert the patch (around 6 June) that caused this, until it's sorted out?
Thanks

Hi Simon, Could the culprit be my bswap patches that Ian pushed on the 6th ? Quickly looking at the history, doesn't look there's lots of things changing primops around this time. -- Vincent
