Steps to Reproduce

poc.sol (fuzzer-generated):

contract test {
    struct S {
        uint8[] a;
        string[2] b;
    }

    S[][] s1;
    S[][1] s2;
    S[1][] s3;

    function f(bytes calldata data)
        external
        pure
        returns (uint256[2][3] memory)
    {
        return abi.decode(data, (super[3]));
    }

    function test2(S[][1] memory _a) public returns (S[][1] memory) {}

    function f(uint[2] memory) public pure {}
}

To reproduce:
solc --bin -o poc poc.sol
