struct Foo {
    static void opCall(int[2][1]) {}
}
void main() {
    Foo(cast(int[2][1])[1, 2]);
}


DMD 2.060alpha gives:

test.d(5): Error: e2ir: cannot cast [1,2] of type int[] to type int[2u][1u] Internal error: e2ir.c 155

A simpler test case shows it's not related to opCall, so I have updated the title:


void foo(int[2][1]) {}
void main() {
    foo(cast(int[2][1])[1, 2]);
}

----------------------------

A similar but not equal case (arrays are 1D):

void foo(int[2] data) {}
void main() {
    int[4] data;
    int[2] data2 = data[0 .. 2]; // OK
    foo(data2); // OK
    foo(cast(int[2])data[0 .. 2]); // Internal error
}


test.d(6): Error: e2ir: cannot cast data[0u..2u] of type int[] to type int[2u] Internal error: e2ir.c 189

I get segfault on this (D2 only, 2.062, Linux/Windows):

void main()
{
    int[2] a;
    a = cast(int[2])null;
}

Reopening, since the code from original description and comment 1 were not fixed (comment 1 part 2 does work though).
