this syntax in this minimal example works (runs) but the error is
still at runtime
#include<iostream>
#include <boost/fusion/sequence.hpp>
#include</usr/include/boost/fusion/adapted/array.hpp>
int main(){
boost::array<double, 2> a;
std::cout
<<boost::fusion::at_c<0>(a)<<' ' //ok
<<boost::fusion::at_c<1>(a)<<' ' //ok
<<boost::fusion::at_c<2>(a)<<std::endl; //gives error but at
runtime (boost/array.hpp runtime assertion)
return 0;
}
