6554	Compiler error dereferencing multi_array value via an iterator	Bill Buklis	Ronald Garcia	"It is currently impossible to dereference/access the values contained in a multi_array via the -> operator from an iterator to the multi_array element. However, use the * operator works.

Example:

{{{
struct data
{
	int	value;
};
typedef boost::multi_array<data, 2> array_type;

array_type	a(boost::extents[4][5]);

// ERROR: Cannot compile this line
a.begin()->begin()->value = 7;

// Compiles successfully
(*a.begin()->begin()).value = 5;

}}}

I'm using Visual Studio 2010. This is an error in both debug and release modes. This is the error:

boost/multi_array/iterator.hpp(40): error C2528: '->' : pointer to reference is illegal
