Testing in progress, I'll let you know how it went. Thanks for the quick fix!

This seems to solve the problem on AArch64. I'll let the others approve if it's the right fix from a compiler-rt perspective.

Looks good to me.

How do we submit this now? Perhaps we need to squash the main fibers patch, check_analyze patch and this into one.

I think squashing would be best, since that makes cherry-picking easy if needed.
