An interesting dilemma. If you apply this patch thoug
Now, ia64's hard-stack-size (rlimit.max) is sum of register-stack size and
memory-stack size. But soft-stack-size (rlimit.cur) accounitng is not sum..
they are accounted independently. This is inconsistent.

But, when ulimit -s is used and stack-base-address-randomization works,
vm layout is sometimes following.

If this happens, register-stack cannot be expanded.
