--- Comment #10 from Andi Kleen <andi-gcc at firstfloor dot org> ---
Yes it has to be fixed. For example with the kernel __kprobes attribute it
could cause a real bug (__kprobes marks function that cannot be safely
instrumented)

We shouldn't inline over different section names either, this could also cause
problems for the same reason.
