How does the custom deleter of std::unique_ptr work?

Question

According to N3290, std::unique_ptr accepts a deleter argument in its constructor.

However, I can\'t get that to work with Visual C++ 10.0 or MinGW g++

Answer 1

This works for me in MSVC10

int x = 5;
auto del = [](int * p) { std::cout << "Deleting x, value is : " << *p; };
std::unique_ptr px(&x, del);

And on gcc 4.5, here

I'll skip going to the standard, unless you don't think that example is doing exactly what you'd expect it to do.
