Hello everyone,

I'm getting an error when trying to get one sub array from a multi_array
with 2 dimensions. This is the code:

//at class constructor
boost::multi_array<char, 2> array2d = new boost::multi_array<char,
2>(boost::extents[x][y]);

...

//at class method
boost::multi_array<char, 1> array1d = array2d[0];

And the error i got: Reference
boost::detail::multi_array::value_accessor_n<T,
NumDims>::access(boost::type<Reference>, boost::multi_array_types::index,
TPtr, const boost::multi_array_types::size_type*, const
boost::multi_array_types::index*, const boost::multi_array_types::index*)
const [with Reference = boost::detail::multi_array::sub_array<char, 1u>,
TPtr = char*, T = char, unsigned int NumDims = 2u]: Assertion `size_type(idx
- index_bases[0]) < extents[0]' failed.

Could anyone help, please?

Thanx,
