Description Maciej (Matthew) Piechotka 2014-09-27 20:53:53 UTC

class Foo<G> {
    class Bar {
        G foobar;
    }
}

Instead of error crashes vala:

test.vala:3.9-3.16: warning: field `Foo.Bar.foobar' never used
        G foobar;
        ^^^^^^^^

This does not crash for me with current vala. The following does however:

class Foo<G> {
    class Bar {
        public G foobar;
    }
    void foo (G foobar) {
        var bar = new Bar();
        bar.foobar = foobar;
    }
}

$ valac e.vala  
**
ERROR:valasemanticanalyzer.c:5675:vala_semantic_analyzer_get_actual_type: assertion failed: (instance_type != null)
zsh: abort (core dumped)  valac e.vala
