Re: [Boost-users] Error (runtime) assigning multi_array to multi_array with smaller dimensions

Apologies all - was a bit too eagerly hitting send. So, quoting myself a bit:

...

//class cpp file //at class constructor array2d = boost::multi_array(boost::extents[x][y]);

I think the problem is that the last line quoted above is an assignment, not an initialisation:

Actually if this was really the problem, the assertions in the assignment operator should cause the construction to fail. But the failed assertion you sent (below) does suggest that array2d is for some reason empty. So I'm a bit puzzled it gets that far?

Reference boost::detail::multi_array::value_accessor_n::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, TPtr = char*, T = char, unsigned int NumDims = 2u]: Assertion `size_type(idx - index_bases[0]) < extents[0]' failed.
