However, when using lldb-server with NativeRegisterContext, while the register values are correct, I don't get a correct working backtrace with it. Without lldb-server, I get a perfect backtrace. (The tested binary uses SEH unwind tables, but DWARF debug info.) Any clues about what might be going wrong there?

Hard to say off-hand, but the first thing I'd check is whether the information about loaded modules and their addresses is making its way into lldb. You can use the "image list" command to inspect that. Then there's the "image show-unwind" command which can show you how lldb will try to unwind for a given function/address. Also, if you enable the "unwind" log channel (log enable lldb unwind), you'll get a trace of what lldb did while attempting to unwind.
