1898 – infinite loop when allocate an array of AA

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;
}

infinite loop, allocate an array of AA

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.
