Non-trivial class hierarchies don't work

[adetaylor]

We can create a subclass C of class B, but probably not if B is a subclass of A and A has virtual methods.

We could handle this one of two ways:

• (simple) When creating B_methods and B_super we could just include all virtual methods from A;
• We could create A_methods and have that as a trait bound on B_methods. That's probably the right way to do stuff, but is a bit more complex to get right.

I don't know if this is the same issue, but I encountered this problem today. My situation occurs when a parent P has a virtual method and I want to use its child C from Rust. autocxx generates an opaque type for C, but I can't use it in any way because the compiler suspects it's uninitialized.

If this is actually a different issue, let me know. I can open a new one.

That sounds like a new issue - please raise one. (It would be even better if you could raise a pull request with a new test in integration-tests/src/tests.rs - the format should be apparent. You can run it just by going to that directory and running cargo test my-new-test-name. Thanks in advance, if so!)
