Comment:

 Boost.Test knows nothing of expression template types internally and so
 can't cope with these.  The fixes are reasonably easy, but it's up to
 Boost.Test's maintainer to decide whether to support this use case or not.
 One fix on your side is to cast arguments to Boost.Test macros to a
 multiprecision type that has expression template support turned off.

 Gennadiy, I'm attaching patches and a test case (which IMO belongs in the
 Boost.Test test suite if you choose to approve the patches), can you take
 a look?

 Also adding Paul Bristow in the loop, as I know he hit this one too.
