After r357703, my bootstrap LLVM build fails with the following output:

I went ahead and enabled assertions, which then fails as such:

It is related to my use of '-march=native', as it does not happen without that
flag.

This still happens on r357851.
Please let me know if I didn't file this correctly or if there is any other
