I'm sure John Maddock will give a fully informed reply to this, but this
boost::multiprecision::expression_template_option ExpressionTemplates = et_on
suggests that you might try setting the 'use expression templates' template parameter to NOT use ET
boost::multiprecision::expression_template_option ExpressionTemplates = et_off
