what's the correct default value for an r-value reference argument?

c++, c++11, default-value, icc, move-semantics

Solution

It appears that icpc 13.0.1 doesn't support universal-initialization syntax in default arguments. This works:

void func(data&& = data());
                       ^^ value-initialization

Problem

Suppose I have a function that takes an r-value argument and I want to provide a default value, how do I correctly specify that? The following works fine with gcc 4.7.0, but fails with icpc 13.0.1. ``` struct data { int _data[10]; data() = default; data(data&&) = default; data(const data&) = default; }; void func(data&& = data{}); ``` icpc complains that ``` error: type name is not allowed void func(data&& = data{}); ^ ``` Is this correct? What is the correct syntax?
