I was able to reproduce the issue with a 64-bit executable compiled with 
the test case in the parent email using Microsoft's Visual Studio 2010 
x64 compiler.  This issue does not appear to be specific to support for 
running 32-bit processes on 64-bit Windows via Wow64.

I have not yet tried to reproduce this on any release of Windows other 
than 64-bit Windows 7 SP1.  I am curious about what other Windows 
releases are affected.  Please reply if you try the test case and are 
able to reproduce the problem on other Windows releases.  So far, I'm 
only aware of the issue being reproduced on multi-processor systems.  I 
suspect the problem can occur on single-processor systems as well, but 
is much less likely to.

Tom.
