Not an expert, but looks like tests 3 and 7 are failing not only for 
multiprecision:

http://www.boost.org/development/tests/release/developer/numeric-ublas.html

Test 7 is removed completely, and has a notion (inside test7.cpp) of 
dependency on open bug #2473 of Boost.Interval . Probably it shouldn't 
be considered at all.

Test 3 fails for some compilers, you may want to check if you use one of 
them.
