Originally discovered while playing with JakobOvrum's enumrate:
https://github.com/D-Programming-Language/phobos/pull/1866

I can reduce it to a simple range that returns a Tuple!(size_t, int). On
win_32, this fails:

//----
import std.typetuple, std.typecons;

alias ET = Tuple!(size_t, int);

struct S
{
    enum empty = false;
    ET front() @property;
    void popFront();
}

void main()
{
    S s; //Or replace with "somthing.enumerate()"
    foreach(i, v; s)
    {
        pragma(msg, typeof(i).stringof);
        pragma(msg, typeof(v).stringof);
    }
    foreach(size_t i, int v; s)
    {}
}
//----

Compilation output:
//----
uint
int
main.d(20): Error: cannot infer argument types
//----

I only tested this on win_32, so I don't know how the other os's (linux), or
versions (64) behave.

While I don't think it is a hugely serious bug, it is also blocker in terms of
portability.
