Summary: Windows reserves and only partially commits thread stack. For detecting more thread stack space for execution,  Windows installs one-shot page as guard page just before the current commited edge. It will trigger STACK_OVERFLOW_EXCEPTION when lands on last 4 pages of thread stack space. StackYellowPages default value is 2 on Windows (plus 1 page of StackRedPages, 3 pages guarded by hotspot) so the exception happens one page before Yellow pages. Same route executed second time will have one more page brought in, this leads same execution with different stack depth(interpreter mode). We need match Windows settings so the stack overflow exception will not happen before Yellow pages.
