Question

Important Information:

• Development OS: Windows 8.1 64 bit
• Target OS: Windows 8.1 64 bit
• IDE: Visual Studio 2013 Professional

Answer 1

If you look at the pre-processed code you'll probably find something like this __declspec(align(16)) in there, requesting to be aligned at 16 bytes while new may not align at that constraint. Accoding to http://msdn.microsoft.com/en-us/library/vstudio/dn448573.aspx you can fix it by Override operator new and operator delete for over-aligned types so that they use the aligned allocation routines—for example, _aligned_malloc and _aligned_free.
