… to hang (pytorch#115124) Let's see if it helps pytorch#114913 The issues on llvm are at llvm/llvm-project#55530 and llvm/llvm-project#69369. In my CI test, I saw the following process hanged: ``` /pytorch/pytorch/.lintbin/clang-tidy -p=/pytorch/pytorch/build --extra-arg -I/usr/lib/llvm-11/include/openmp --extra-arg

user may not know which line of code called collectives in a big code base. When debugging, we can print python-cpp stacktrace in case user call ``ProcessGroup.reduce`` instead of ``torch.distributed.reduce``
```
LOG(INFO) << "ProcessGroupNCCL::_allgather_base stacktrace: "
<< get_python_cpp_trace();
```
output (using _allgather_base as an example): one example python-part trace is ``all_gather_into_tensor from /data/users/weif/pytorch/torch/distributed/distributed_c10d.py:2838``
