Returning value transitively through assignment doesn't work

[aubade]

The following code compiles in dmd and gdc, but not the current ldc beta, on Linux x86-64:

struct rectarray(T) {
    T[] data;
    size_t width;

    auto ref T opIndexAssign (ref T value, size_t col, size_t row) {
        return data[row * width + col] = value;
    }
    auto ref T opIndexAssign (T value, size_t col, size_t row) {
        return data[row * width + col] = value;
    }
}

void main() {
    rectarray!int wrap;
}

instead, it gives the error:

test.d(6): Error: this.data[row * this.width + col] = value is not an lvalue

Does not compile with dmd 2.064.2. It's a bug fixed in a later version.

[aubade]

Oh, whoops! Sorry, I assumed that since it claimed the same dmd version, the current gdc release would manifest problems the same way.

[redstar]

The current gdc release should also be based on 2.064.2. A pull request for gdc based on 2.065 was created yesterday. Don't know why it works for you.
(BTW: If you compile ldc from source, then you can use the merge-2.065 branch. This should contain the fixed frontend.)

Now works on Git master.
