Crash on simple C++ code snippet

Indexing segfaults for this simple test repository:

$ codebase-memory-mcp cli index_repository '{"repo_path": "/tmp/codebase-test"}'

Segmentation fault         (core dumped) codebase-memory-mcp cli index_repository '{"repo_path": "/tmp/codebase-test"}'

In /tmp/codebase-test there is only a single file test.cpp:

template<typename T, typename U = int>
U f(auto, T t) {
    return t;
}

int main() {
  if(f( 1, 2 ) != 2) return 1;
}
