It looks to me like there is a regression with multi_array in boost 1.42
using the MSVC10 RC. The problem is when you assign a sub_array to an
array. This code works fine on MSVC9 and Intel 11.1 on windows.
Any easy patches that could fix this, or am I missing something?
#include
int main(int argc, char* argv[])
{
boost::multi_array f_values(boost::extents[5][6][7]); //A
boost::multidimensional object
boost::detail::multi_array::sub_array sub_f = f_values[2];
//Works
boost::multi_array sub_f2 = f_values[2]; //Fails, used to work
}
