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
