t/dateformats.t fails on 32bit arm

[Grimler91]

Hi, the dateformat tests are failing when I try to install biber on android arm. On android aarch64 (arm 64bit) the installation and tests succeeds without problems.

The full output I get when trying to install with cpanm --verbose is:

cpanm (App::cpanminus) 1.7044 on perl 5.032000 built for arm-android

I managed to install biber 2.13 or 2.14 on the same platform without problems around a year ago or so, but when I try these versions now I get the same errors from the dateformats test.
I guess this indicates that there is something in a dependency that has changed rather than in biber. Do you have any suggestions how I can investigate it further?

Please let me know if I can provide any more information, or if there is anything I can try.

I'd have to double check, but I think I'm getting the same errors when building on 32bit Linux. I always assumed this would be due to integer overflow in the Extended years. If the integers overflow in a way that alters the sorting of the test entries that would also explain the wrong extraname values. For now I've always ignored these test failures.

Maybe we could try and use year examples that work for both 32-bit and 64-bit integers.

Yes, this is 32/64 int differences I think which means that the failure is harmless since the reference data for the tests assumes 64-bit.

Thanks, I assumed the error happened due to my platform (android arm), but apparently not then!

Alright, thanks, then I'll just ignore this test failure.

Feel free to close the issue (or leave it open if you want to update the tests to work on 32bit as well).
