           Summary: Chaos on struct with multidimentional static array
                    initialization from its element
           Product: D
           Version: D2
          Platform: All

            Status: NEW

          Severity: major

struct S
{ int[2][1] a21; }

void main()
{
    int[2][1] a21 = [1, 2]; // ok
    static assert(!__traits(compiles, a21 = [1])); // ok

    static assert(!__traits(compiles, { static S ss = { a21: [1]}; })); //
assert fails, creates a21 = [[1, 0]]
    static S ss = { a21: [1, 2]}; // Error: array initializer has 2 elements,
but array length is 1
    S s = S([1, 2]); // [Issue 11105] Error: cannot implicitly convert
expression ([1, 2]) of type int[] to int[2u][1u]
}

Some indices ICEs the compiler:
---
struct S
{ int[2][2] a22; }

static S ss = { a22: [1]}; // Assertion failure: 'sz == vsz || sz * dim <= vsz'
on line 144 in file 'todt.c'
