Issue

Hi, I'm trying to build pendulum for Fedora Linux with Python 3.14.0b1.
I see two issues happening there.

test_from_format results in Segmentation fault for two parameters:

        ("1234567890", "X", "2009-02-13T23:31:30+00:00", None),
        ("1234567890123", "x", "2009-02-13T23:31:30.123000+00:00", None),

When removed these, the test suite runs successfully, but with two more failures:
