Function type variable call failed.

[Subway2023]

Version: v0.3.3: Atlantis

contract C {
    function g(string calldata) external returns (bool) { return true; }

    function main() external returns (bool) {
        function (string memory) external returns (bool) ptr = this.g;
        return ptr("testString");
    }
}

Reproduction: I set up a Solang compilation and execution environment to test the program.

solang/target/debug/vmRunNoPara test.sol C main

The execution error is as follows:
