Did the patch as posted fail, or did it fail when you changed the GUC to follow
the fips mode? I assume it's the latter since the code in question doesn't
care about FIPS at all (hence this patch). Re-testing it again against OpenSSL
3.4 with FIPS enabled as well as disabled I can't reproduce any failure.

The work which was done was to ensure that the tests passes regardless of if
FIPS is enabled or not, they were not designed to test FIPS.
After thinking about I don't think we need an alternative output file since it
won't add any testing:

If we add such an alternative output we also need the other case where FIPS is
disabled and the functions work, which means we add no test coverage at all as
both options are allowed to pass.
