--- Comment #3 from Avi Kivity <avi@cloudius-systems.com> ---
My code has this:

    // There is no caller of main() in this context. We need to annotate this
frame like this so that
    // unwinders don't try to trace back past this frame.
    // See https://github.com/scylladb/scylla/issues/1909.
    asm(".cfi_undefined rip");

Should I use some other annotation to terminate the frame unwinding
information?
