--- Comment #2 from Reid Kleckner <rnk at google.com> ---
r370409 should fix these cases.

I think when you were working on r270109 we were measuring code size of
i686-windows-msvc for chromium, which uses /Oy- to preserve frame pointers, so
the stack frame was frequently not reserved, which avoided this case.
