How to allocate an array of AA?

1)
I tried two ways (new, and setting array length), in both cases the code
compiles, but the executable seems run into infinite loop, and never finish.

2)
how to new an AA? what's the syntax?

$ cat mapbug.d

void allocAA() {
  int[int][] maps;
  maps = new int[int][3];
  maps.length = 3;

  int[int]* mapsp;
//mapsp = new int[int];  // this line need size of rightmost array, not type
int
}

int main() {
  allocAA();

  return 0;
}

As for your second question, I'm not sure that there's a general way.  But

    mapsp = (new int[int][1]).ptr;

should work once the underlying bug is fixed.  Meanwhile, a workaround is

    int[int][1] mapsa;
    mapsp = mapsa.dup.ptr;

But since the main bug you're reporting has already been reported and voted on, I'm marking this as a dupe.

*** This bug has been marked as a duplicate of 929 ***
