[ICE]: Assigning to mapping in uninitialized storage struct causes error

[Subway2023]

Solang version: v0.3.3-70-g32a45ea1
Description: c.a[0] = new uint; causes a compilation error.

contract C {
    struct S { mapping(uint => uint[]) a; }
    function f(bool b) public {
        S storage c;
        assembly {
            c.slot := 0
        }
        c.a[0] = new uint[](1);
    }
}
