I'm made a basic and extended class. The basic class had a private setter that the extended class tried to override. This is an error from my side, but when I generate c-files, the valac compiler doesn't complain about this error.

[basic_class.vala]
using GLib;

public abstract class Basic_class : Object {
    public abstract string some_var { get; private set; }
}

[advanced_class.vala]
using GLib;

public class Extented_class : Basic_class {
    public override string some_var { get; private set; }
}


steps to reproduce:
- valac -C basic_class.vala advanced_class.vala
- gcc -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -c basic_class.c 
- gcc -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -c advanced_class.c

expected result:
- valac complains about overriding a private setter

actual result:
- gcc complains: advanced_class.c:74: warning: ‘basicclass_set_some_var’ used but never defined
