The OED (old entry) and American Heritage only give the /ɹik/ pronunciation. Merriam-Webster gives that and the /ɹek/ pronunciation.
Garner marks /ɹek/ as “Stage 1,” which means he considers it rare and a minority pronunciation, but as usual, he gives no evidence for this conclusion.
I’d say it’s definitely newer, but I don’t think it’s all that new or all that rare. I’ve heard it all my life, and until I looked it up right now, I had never been sure which was considered the standard pronunciation.
