import torch crashes or hangs with spindle

Nobody has claimed this yet.

import torch sometimes works and sometimes crashes randomly with the following error on 128 nodes.
Could you tag if its an already known issue?

I used commits till 92bda828efcef13e3b2f83e0c01b8280665c290c on devel branch

pytorch 2.5

Start by reproducing the intermittent failure with the provided spindle and mpiexec commands on 128 nodes, then inspect torch/__init__.py and torch/torch_version.py where the traceback occurs. Determine whether spindle is introducing null bytes into the imported source and document whether the behavior is a known issue, with a reliable reproduction or explanation as the outcome.
