Please describe the problem:
The following legal vala code leads to illegal c code:

using GLib;

const KeyFile keyfile = new KeyFile();

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


Steps to reproduce:
gint _main (char** args, int args_length1) {
        GKeyFile* _tmp0;
        GMainContext* _tmp0;
        GMainContext* context;
        gint _tmp1;
        _tmp0 = NULL;
        _tmp0 = NULL;
        context = (_tmp0 = g_main_context_new (), (_tmp0 == NULL) ? NULL : (_tmp0 = (g_key_file_free (_tmp0), NULL)), _tmp0);
        return (_tmp1 = 0, (context == NULL) ? NULL : (context = (g_main_context_unref (context), NULL)), _tmp1);
}


int main (int argc, char ** argv) {
        g_type_init ();
        return _main (argv, argc);
}

Does this happen every time?
