ORCC 0.4.9 is used on this system. Could you try with Orc 0.4.10? Unfortunately, I don't have a quick way to downgrade my local Orc version to verify? If this is not possible, we can just bump the patch to 0.4.11, which was released a while ago (and is what I'm using). BTW, for 0.9.22 and current stable-queue, the Orc stuff will not get used for anything on ARM. Cheers, Arun
