Reducing repros takes some time, but it's usually not very hard - I just have to throw away irrelevant code, but it's code that I'm familiar with, so I know how to chop it down. And in return, I get fixes quite rapidly. We don't expect customers to be able to reduce repros all the way down to library-free, but if you can chop out Boost, that really helps.

I did reduce the original problem to code and VC++ headers to make it 
easier to fix.
