4874	multi_array compile errors using Visual C++ 2010 in debug mode	chrislu	Ronald Garcia	"This is a long standing problem and it should have been fixes already [1], but in boost release 1.45 it still exists.

When using a multi_array and engaging the copy constructor or assignment operator of a multi_array in debug mode on Visual C++ 2010 the following errors are generated. This was done using the boost 1.45 release on Visual C++ 2010 on Windows 7 x64 targeting a x64 build:
