Pavel Afremov updated HARMONY-4264:
-----------------------------------

    Attachment: 0001-Size-of-the-stack-required-for-guard-page-setting-wa.patch

One page on the stack is not enough to create SOE on Windows x86-64.

On Windows x86-64.DRL VM can't process SOE, because one page on the stack is not enough to
create exception.
Move guard page and increase guard stack is not possible on the Windows by standard mechanisms.
