I've now also tried under a PkgBase 14.1-RELEASE-p6 based
poudriere aarch64 jail:

[00:05:29] [01] [00:00:00] Building   lang/python310 | python310-3.10.16
[00:11:27] [01] [00:05:58] Finished   lang/python310 | python310-3.10.16:
Success

Again: no problem observed with both lto and 
--enable-optimizations in use (including PGO activity).

It seems that there is more to the context that
contributes to the failing cases.



FYI: when I watch with top I see examples of:

./python -m test --pgo --timeout=1200{python}
