I’m currently investigating stack frame setup handling for async support and a few other threads of work. I have a big backlog of other items as well. It will likely be a while before I can get back to the interpreter without others helping drive all the other work.
If you are interested, the problem is a couple of separate items. The module loading needs improvement in lldb (upstream), the library search handling seems to not be working (downstream), and there may be some more issues on the JIT side (upstream). You might be able to bisect the changes that occurred somewhere between 5.1 and 5.4 that regressed the interpreter, but it’s unlikely to help at this point - it has been too long.
Help is definitely welcome
