---------------------------------------------------+------------------------
 A phoenix expression [1] applied to valarray<double> [2] leads to a
 segfault.

 [1]  boost::phoenix::at_c<0>(arg1) += boost::phoenix::at_c<1>(arg1) /
 val(mass) * arg2

 [2] std::tuple<std::valarray<double>, std::valarray<double>>

 A simple example is attached triggering the problem. (When compiled with
 gcc 4.6 or 4.7)
