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.
