Bug report

Bug description:

The PGO test suite fails on the test_datetime tests; in particular, the test_strftime_y2k test cases. It looks like the padding is wrong:

cpython-3.14> AssertionError: '1-01-01' != '0001-01-01'

I believe this is related to:

Note this is occuring in the python-build-standalone builds. I have not reproduced it independently. This isn't a problem during our x86_64_v4 builds because we're not running PGO on them. The normal x86_64 build is working.
