Issue ID: 13393
Summary: std.algorithm.joiner Assertion failure in popFront()
when using with cartesianProduct
Product: D
Version: D2
Hardware: x86_64
OS: Windows
Status: NEW
Severity: regression
Priority: P1
Component: Phobos

Here is a reduced test case.
-------------------------------------------------------
import std.algorithm;
import std.range;
import std.stdio;
void main()
{
[cartesianProduct([0],[0],[0])].joiner.writeln;
}
-------------------------------------------------------
Fails with core.exception.AssertError at std\algorithm.d(3804): Assertion failure
in popFront()
in pure nothrow @nogc @safe void
std.algorithm.joiner!(std.algorithm.cartesianProduct!(int[], int[],
int[]).cartesianProduct(int[], int[],
int[]).Result[]).joiner(std.algorithm.cartesianProduct!(int[], int[],
int[]).cartesianProduct(int[], int[], int[]).Result[]).Result.popFront() at
D:\D\dmd2\windows\bin\..\import\std\algorithm.d(3805)

Tested with phobos commit f0e9039227ee0fee664cde2d29a733cc69873912
Current master on dpaste works fine http://dpaste.dzfl.pl/b2ced50be1a6
