[1, 3]

cat > bug.d << CODE
int[] ary = [0: 1, 2, 1: 3]; // fails during data emission in glue layer
void main()
{
    import std.stdio;
    writeln(ary);
}
CODE

dmd -run bug
----
bug.d(1): Error: duplicate initializations for index
----

Both programs should have the same result and to avoid silently overwriting an
already initialized element, both programs should error.
