Hello Sorry for late replay. It was very nice weekend for me :)

- I could not get the unwind failure that you have mentioned (with the overflow happening in the first two lines) though I played around with the test, but that may depend on what the specific setup of the stack is at that point?
I rebase and recompile my version of DRLVM. And I can't reproduce it too. On my previous version some magic was required to reproduce it. I added several variables into main functions and into function "func". This "magic" was different for different build and should be tuned after a small changes in VM code. Now I can't reproduce it using this magic.
... - But I also saw that you fail the JIT if you don't have 256 K of free stack space. The default Windows stack size is only 1 MB. Do we need to fail a compile of 10 lines of bytecode if we don't have 1/4 of the stack available? Maybe this can be less strict, or some heuristic based on method size? What do you think about this?
Yes it's 1/4 of the stack. But in my test current implementation provide recursion with depth = 704220. Is more deep reqursion required anywhere? I think its very unlikely . In any case if more deep recursion will be required in the future, we can tune thread stack size for windows build. Thanks. Pavel Afremov
