In my use of Boost over the last year or so, these internal compiler errors 
happen pretty much constantly.  As you've already discovered, turning off 
precompiled headers or switching compilation modes can make them go away 
(but not always).  Sometimes switching the order of lines of code can clear 
them up.   Sometimes I haven't been able to solve the problem at all and 
have had to either give up or vastly restructure my code.

My simple-minded analysis is that the BPL really stresses C++ compilers and 
sometimes MSVC++ just falls down.

Good luck,
