Maybe also try using the `CallGraph` ctor as well which uses `addToCallGraph`.
```cpp
CallGraph::CallGraph(Module &M)
: M(M), ExternalCallingNode(getOrInsertFunction(nullptr)),
CallsExternalNode(std::make_unique<CallGraphNode>(this, nullptr)) {
// Add every interesting function to the call graph.
for (Function &F : M)
addToCallGraph(&F);
}
```
Maybe passing it `TU->getOwningModule()` would work.
