Weird.  Any chance you're doing a bootstrap build?

There was an earlier bootstrapping issue with this branch. We had
turned on -std=c++1y by default, and it was causing some conversion
errors with lvalue references to bitfields in libasan.

This doesn't *look* like a regression caused by concepts -- I don't
think I'm touching the initializer code at all.
