static_assert(std::is_abstract) causes a compiler error in Visual Studio 2013

Question

When compiling this line of code in Visual Studio 2013:

static_assert(!std::is_abstract<int>(), "test");

this compiler error is output:

expected constant expression

But the code snippet is presented as an answer in this SO question. Is this a bug in the MSVC++ compiler? Is there a workaround?

Answer 1

MSVC has no constexpr, use std::is_abstract< int >::value
