Hi Mike, some of our internal bots are having an issue with this commit:

  error: no member named '__err' in '__darwin_arm_exception_state'
    return ucontext->uc_mcontext->__es.__err & 2 /*T_PF_WRITE*/ ? WRITE : READ;

I'd really appreciate it if you could shed some light on this. I see two definitions of this structure in the OS, and neither contain '__err'. Can you share which OS you built this code against?
