Comment:
OK, I got my laptop back :-) Patch validates, but before I push it I want
to make a few more tests to see that it does the right thing.
> And here's an ugly PoC patch that moves the self-loop label below the
stack check:
Could you explain how and why this works? I mostly interested in knowing
how does it guarantee to place self-loop label after stack check but
before heap check. I don't have more time to investigate this at the
moment but if the patch is ready and working it would be good to have it
pushed. Once I push your patch for loopification I'll close this ticket
and start a new one for moving self-loop label after the stack check.
