DEBUG: Cython failures
Trying to get a Cython reproducer for https://github.com/pandas-dev/pandas/pull/61249
First piece of repro from [8837a71](https://github.com/pandas-dev/pandas/pull/61262/commits/8837a71a9797cdc82f331c1205759e473e5fa219)

```cython
cpdef timedelta debug_2():
    cdef int64_t val = -420000000000
    us, remainder = divmod(val, 1000)
    if remainder >= 500:
        us += 1
    return timedelta(microseconds=us)
```

Windows 3.13t: `datetime.timedelta(microseconds=906795)`
Other Platforms: `datetime.timedelta(days=-1, seconds=85980)`
 Opened https://github.com/cython/cython/issues/6786 as a result of this investigation so closing
