this happens when building libclc from meta-clang I also saw random build failures in qtbase which is perhaps unrelated but could be this one too Third issue is https://errors.yoctoproject.org/Errors/Details/701889/ I wonder if uninative version of glibc should be first built with this change if we really want to pursue it. Also send a BIG warning to community on breaking this backward compatibility, for some it might be helpful to get this notification now than next year.
