================
Comment at: lldb/source/Plugins/Trace/intel-pt/IntelPTDecoder.cpp:149
+        thread.AppendError(insn_index, make_error<IntelPTError>(time_error, insn.ip));
+        thread.AppendInstruction(IntelPTInstruction(insn));
         break;

> Yea I was doing that before, the idea was to send those variadic args to emplace_back but that wasnt working. I introduced this to avoid having 2 Appends since we already have 2 constructors which fulfill that requirement, and I can change this to std::move to avoid copies if thats a concern
Yes, use the same pattern than emolace_back uses with a parameter pack
