================
Comment at: clangd/tool/ClangdMain.cpp:86
+      return nullptr;
+    Index = AsyncLoad.get();
+    return Index.get();
----------------
I believe is a data race (multiple threads may run this line concurrently).
You would want some synchronization around this, `std::shared_future` could be a good fit
