Fatal error: exception Out of memory when targeting Hashlink

[skial]

It looks like two classes with duplicate private types causes this error when targeting hl. I've setup a repo with all the code and generated dump files.

// Main.hx
class Main {

    public static function main() {
        new Test1().test();
        new Test2().test();
    }

}
// Test1.hx
class Test1 {

    public function new() {}

    public function test() {
        var _foo:Foo = new FooLike();
    }

}
// Test2.hx
class Test2 {

    public function new() {}

    public function test() {
        var _foo:Foo = new FooLike();
    }

}

With both Test1.hx and Test2.hx having these two types at the end:

private typedef Foo = {
    function make<T>(v:T):Foo;
}

private class FooLike {
    public function new() {}
    public function make<T>(v:T):FooLike return this;
}

And the stack trace.
