We are seeing this failure at the end of the nightly Linux build smoke test:
https://github.com/pytorch/FBGEMM/actions/runs/12049477907/job/33621272179

WARNING:root:Could not the library 'fbgemm_gpu_py.so': /lib64/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /__w/_temp/conda_environment_12049477907/lib/python3.9/site-packages/fbgemm_gpu/fbgemm_gpu_py.so).  This may be expected depending on the FBGEMM_GPU variant.

Smoke test is green but this is actually hard error. Manifest in torchrec here:
https://github.com/pytorch/torchrec/actions/runs/12049473108

Looks like after switching to pytorch/manylinux-builder:cpu containers this does not work correctlty. Previous nightly run was not showing this error: https://github.com/pytorch/FBGEMM/actions/runs/12029739812/job/33535665003
