Hello David,

On the second thought, I replaced boost_python.dll built with IDE
projects with boost_python.dll built by bjam, and the assertion
disappeared. Oh well.

Then I put boost_python_debug.dll built with IDE into the app dir
(renaming to boost_python.dll, of course), and tried again. No
assertion.

Putting back release version of the dll brought the failure back.

So, the assertion only appears when using release version built using
\libs\python\build\VisualStudio\boost_python.dsw

I don't claim that it is Boost code that has an error---but surely
there _is_ a bug somewhere in there? Maybe MSVC projects, maybe MSVC
itself :) .
