Not sure if its any help but just tried compiling this with VS2010 and VS2012

>From VS command prompt (with boost version 1.51 pathed into include and lib)

cl test.cpp /EHsc /O2

and resulting test.exe is fine (with or without /O2)

So does look like a problem with vs2008 specifically (sorry don't have one available to try any longer)
