This compiles for me without error. When it runs, I get a stack overflow. The reason looks clear - foo(Args) is recursively calling itself. I don't
think it's a bug in dmd.


I retried above code using new beta on two environments.

Mac OS X 10.6.8 causes segmentation fault, but
Scientific Linux release 6.0 64bit works fine.

Does D allow above code?

If I understand that correctly then the chosen overload differs.
This prints "variadic" for me. Can you recheck this for other setups
and file a bug.

IMHO this should be an ambiguous overload error.

import std.stdio;

struct S
{
    void foo(V)(in V v)
    {
        writeln("non-variadic");
    }

    void foo(Args...)(auto ref const Args args)
    {
        writeln("variadic");
    }
}

void main()
{
    S s;
    s.foo(10);
}
