Test case:

-----------------------------
struct D6375 {
    int[] arr;
}
A6375 a6375(int[] array) {
    return A6375(array);
}
struct A6375 {
    D6375* _data;
    this(int[] arr) {
        _data = new D6375;
        _data.arr = arr;
    }
    int[] data() {
        return _data.arr;
    } 
}
static assert({
    int[] a = [ 1, 2 ];
    auto app2 = a6375(a);
    auto data = app2.data();
    return true;
}());
-----------------------------
Bus error: 10
-----------------------------

This is essentially the trimmed down version of the unit test for std.array.appender, running in CTFE. The segfault is due to StructLiteralExp::getField in expression.c:

   if (e->type->castMod(0) != type->castMod(0) && type->ty == Tsarray)
   //     ^^^^ e->type is NULL

Running e->semantic() once fixed the issue, but I'm not sure if this is the best solution.
