I don't have a MSVC 7.1 copy so I cannot help here. :(
Have you tried with my test case? Does it work? If so, I'm confident
the original problem will be solved as well. In case you want to give it a try,
the original code where the problem popped out is given in

http://lists.boost.org/boost-users/2005/04/11326.php

Also, I don't know if the patch should be also applied to MSVC 8.0.
