I've been running various builds of VC11 for a bit now and though there are a few more failures than VC10, its not too bad. However, I just got a machine up with VC11 using the address-model=64 flag and every single test fails.  

If you look at the trunk results (http://www.boost.org/development/tests/trunk/developer/summary.html), you'll see the problem child runner: teeks99-3-win7-64on64. There are two other testers (teeks99-2-win7-32on64 and teeks99-7-win7-32on64) that are running from the same VM image but without the address-model variable and they seem to be nominal. 

I'm not sure what I should check from here. I was thinking it might have been a problem with the bjam executable not being updated for VC11 correctly, but I was able to build the binaries for VC11 with the address-model variable just fine, so that makes me think it might be something more on the regression tests side. Any ideas?
