I'm making best efforts to fix the problem, but it seems to me that the current
check_stack() doesn't fit to arm64 due to the differences in stack frame usage
on architectures.
Although my current patch doesn't solve all the issues I've noticed so far,
I'd like to get any comments about whether I'm doing it the right way.
Please take a look at my new vesion (v2) of RFC.

Thanks,
