Hi Phillip, I've run into this myself outside of boost compilation.

The issue stems from the default options for the new MS-compile not
supporting synchronous writes to PDB files.
I believe this issue only arises during the compilation stage, in Visual
studio I pass it the /FS option it desires.

I believe you *might* be able to use CXXFLAGS to pass the FS command to the
compiler.

Eg:

b2 -j2 release
*cxxflags=/FS*
That said, I haven't tested this method myself (yet). (if this occurs
during the linking stage you may need to pass linkflags=/FS also)

If I may ask, are you attempting to compile the static libraries? using
multi-compilation to accelerate the process? If so you may wish to consider
using --with-*LIBNAME* for just the libraries in question.
eg:
b2 --with-aiso --with-thread --with-filesystem
This will make the process much faster if you do not need the entire
collection.

Yours,

John
