I'm not sure. I'll have to check. boost is obviously compiled with VS 2008 via bjam and my code directly in VS 2008. 

Note that I switched compilers to VS 2010 and everything now works as expected. More specifically, I recompile boost and my own code with VS 2010 and I no longer get any errors in debug or release modes.

thanks,

Nick
