I created a struct with an anonymous function member variable:
struct S
{
    const foo=function(int x,int y,int z)=>x;
}

When I create an instance of S and call the function with three arguments, the
arguments get shifted: x gets junk data, y gets the first argument, z gets the
second argument, and the third argument is lost.

If I declare foo in the global scope of the module, the arguments are passed
the way they should - x gets the first argument, y gets the second argument, z
gets the third argument.

If I declare foo as a member variable of a class, I get a segmentation fault
when I try to call foo.

Making foo a static, shared, or __gshared member does not solve the problem.

Declaring foo's type explicitly *DOES* solve the problem:
int function(int,int,int) foo=function(int x,int y,int z)=>x;
this does work.

I have encountered this bug on DMD64 D Compiler v2.059 running on Arch Linux
3.3.8-1.
