----- symptom ----

dmd  -ofsolver solver.d
Internal error: ../ztc/type.c 320

----- conditions -----

ICE occurs in type.c line 320 during array append operation of structs.

Error only occurs when all these conditions are met:

1. One object must be a list, the other a single object.
2. Value.sizeof must be < 3.
3. The single value is returned from a function or method.

----- solver.d -----

struct Value {
    //int a; // does not produce error
    byte a;  // produces error (also, short would produce an error)
};

Value single()
{
    Value v;
    return v;
}

int main(string[] args)
{
    Value[] list;
    Value single2;

    Value[] buffer = single() ~ list; // error
    Value[] buffer2 = single2 ~ list; // not an error

    return 0;
}
