Strange, indeed.

Still, it's clear that it is something to do with the project settings and/or MSVC2012 rather than the code. I hope you manage to figure it out.

I will however make the necessary code changes to allow AngelScript to be used in Windows Store applications too, so I thank you for bringing this to my attention.

I would imagine it's MSVC2012 (probably just mine, as you weren't experiencing the problems). No need to thank me, I should be the one thanking you for writing such an amazing piece of software and letting everyone use it free of charge.
