[Subway2023]

Version: v0.3.3: v0.3.3-70-g32a45ea1
Description: Due to the excessively large size of uint[2100],** the assignment x[0][0] = 1; causes a compiler error.

contract C {
    mapping(uint => uint[2**100]) x;
    mapping(uint => uint[]) y;

    function mutate() public {
        x[0][0] = 1;
    }
}
