Java binary compatibility - RFC on proposed solution to covariant return type using invokevirtual semantics
I'm trying to evolve an API. As part of this evolution I need to change the return type of a method to a subclass (specialize) in order for advanced clients to be able to access the new functionality.
Example (ignore the ugly :

Reference counted structure exposing a POD interface
I currently have a structure that declares a copy constructor, and a destructor, and keeps a reference count to a pimpl object. This allows me to pass this structure around by value. I need to refactor it because I want it to have a POD interface…

Is it possible to share a C struct in shared memory between apps compiled with different compilers?
I realize that in general the C and C++ standards gives compiler writers a lot of latitude. But in particular it guarantees that POD types like C struct members have to be laid out in memory the same order that they're listed in the structs…

Say a shared library contains the following lines:
const char* const arr[] =
{
"one",
"two",
"three"

Does changing the return type of a function for a child type breaks binary compatibility?
Let's go straight to it :
Old code :
public interface IFoo {}
public class Foo : IFoo {}
...
public static IFoo Bar() { return new Foo(); }
New code :
public static Foo Bar() { return new Foo(); }
Obviously there should be no problem here,…

I'm curious to know if anyone is working on compatible interface layers for STL objects across multiple compilers and platforms for C++.
The goal would be to support STL types as first-class or intrinsic data types.

Is the official binary incompatibility between VS2017 and VS2015 app vs. dll accurate?
TL;DR - The MS docs state that binary compatibility between VS2015 and VS2017 libs is one-way, while I'd assumed it is necessarily two-way. Where's the catch?
First, for background:
Any MSVC++ built libraries are officially binary compatible…
