[issue18306] os.stat gives exception for Windows junctions in v3.3

Hello Tim,

The fact that it works on 64-bit Python obviously reduces the priority. 
I will make a point of choosing the 64-bit version in the future.

FWIW. I'm dubious about the problem being solely attributable to WOWs 
handling of junctions because my Python 3.2 (that doesn't have the 
problem) is also 32-bit. There must be something else, even if that 
something isn't going to be fixed.

Thankyou for spending time on this.

John

If I run 32-bit Python on 64-bit Windows, I get the error you describe because Windows will silently redirect the 32-bit Python process towards %windir%\SysWow64 where the junction (or, possibly, its target) does not exist.
