empty slice ptr cast with offset of 0 fails

[BarabasGitHub]

Zig compiler version 0.3.0+5703ab1d

test "empty slice ptr cast with offset of 0" {
    const empty_slice: []u8 = [_]u8{};
    const p: [*]u8 = empty_slice.ptr + 0;
    const t = @ptrCast([*]u8, p);
}

gives the error:
ptr cast empty slice offset with 0...cast causes pointer to be null

however this works

test "empty slice ptr cast with offset of 0" {
    const empty_slice: []u8 = [_]u8{};
    const p: [*]u8 = empty_slice.ptr;
    const t = @ptrCast([*]u8, p);
}

Doesn't make sense to me.

if you add & on the array add _ = t; this works on 0.9.0-dev.1343+75cecef63
