struct S
{ @disable this(); }

struct Z(Ranges...)
{
    Ranges ranges; // line 6

    this(Ranges rs)
    { ranges = rs; }
}

struct F(alias pred)
{ this(int[] = null) { } }

Z!Ranges z(Ranges...)(Ranges ranges)
{ return Z!Ranges(ranges); } // line 16

void main()
{
    z(S.init, F!(gv => true)()); // line 20
}
---

Output:
---
main.d(16): Error: field Z!(S, F!((gv) => true))._ranges_field_0 must be
initialized because it has no default constructor
main.d(20): Error: template instance main.z!(S, F!((gv) => true)) error
instantiating
---

Output if line 6 is `Ranges ranges = Ranges.init;`:
---
Internal error: e2ir.c 5321
---

Output if line 6 is `Ranges ranges = void;`:
---
Assertion failure: 'v->type->ty == Tsarray && vsz == 0' on line 470 in file 'todt.c'
---

This causes e.g. error on `zip` over non-default constructable range and filter result.
