Make a descriptive title that summarises the bug as a whole.
Done.
Explain the bug in as much detail as you can in the body of the issue.
I think the title explains most of it. By "raw pointer usertypes" I mean usertypes that only have factories producing raw pointers. You can see my use case in the Compiler Explorer example.
Include Compiler/IDE (Visual Studio, XCode...), Build and Deployment System, Language (C++, Objective-C++), and any special defines you have set.
I'm using g++ on Linux with CMake.
