// This test was written because on Windows with Subzero, we would get a crash when executing a function

// needed for the stack whenever an access is made in a "guard page", at which point the page is committed,
// and the next 4K page becomes the guard page. If a stack access is made that's beyond the guard page,
// a regular page fault occurs. To fix this, Subzero (and any compiler) now emits a call to __chkstk with
// the stack size in EAX, so that it can probe the stack in 4K increments up to that size, committing the
// required pages. See https://docs.microsoft.com/en-us/windows/win32/devnotes/-win32-chkstk.
