Vala compilation fails with vala_ccode_array_module_real_get_array_length_cvalue: assertion failed

Question

I'm working on developing a library for interfacing with Pandora. I'm basing my blowfish code off of the python library, but I'm having trouble compiling it. Vala reports no errors until it tries to generate C source files. This is the error I am getting:

nathan@nathan-laptop:~/projects/libpanda$ valac --thread lib/crypto.vala -C -v

You can find the source code in my git repository here. I'm not sure if this is a bug with vala itself or my code. I have a feeling it has something to do with multi-dimensional arrays, as it was compiling yesterday when the sboxes were single-dimensional arrays.

EDIT: It looks like this is an issue with vala itself. It appears you cannot assign the value of a const multi-dimensional array to another variable:

public class TestClass : GLib.Object{
    public static const int[,] ff = {{1,2},{3,4}};

    public int[,] asdf;

    public TestClass(){
        asdf = TestClass.ff;
    }

    public static int main(string[] args){
        var t = new TestClass();
        return 0;
    }
}

Answer 1

As stated in my edit above, it appears you cannot assign the value of a const multi-dimensional array to another variable:

public class TestClass : GLib.Object{
    public static const int[,] ff = {{1,2},{3,4}};

    public int[,] asdf;

    public TestClass(){
        asdf = TestClass.ff;
    }

    public static int main(string[] args){
        var t = new TestClass();
        return 0;
    }
}

I have filed the bug with the vala team here
