?!?
First, I don't get this failure. Andrey, what is your precise target
configuration?
Martin -- the code you show is exactly what is should be.
In the "before" case we have a stack allocation of 13768 bytes, then probes
into that allocation. That is not safe WRT stack-clash as you could get an
async signal between the allocation and probing points and the async handler
would be running with a clashed stack/heap.
The "after" case we see 4 distinct allocations and probes, which is exactly
what we want.
