Asunto: [boost] boost.format(): Unexpected assert failure?

> fmt % Blank; // This line causes an assertion in MSVC8

Hello Jon, I think this problem has been reported in the past
and is already fixed both in the CVS main trunk and the
1.34 branch. You might want to check it out by yourself by
replacing your local copy of boost/format/feed_args.hpp with
the version at:

(press download on the page referred to by the link above).

Hope this helps,
