The reason this was not a problem before was that boost/multiprecision/rational_adaptor.hpp uses Rational, which used to include math/common_factor_rt.hpp, but no longer does. Either math:: should be made integer::, the include added, or both. ",Bugs,closed,To Be Determined,multiprecision,Boost 1.57.0,Problem,fixed,,
