Pandas version checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest version of pandas.

  • I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

>>> a = pd.Series([10.2, 100.2], dtype=pd.ArrowDtype(pa.float32()))
>>> pd.to_datetime(a)
Fatal Python error: Cannot recover from stack overflow.
Python runtime state: initialized

Issue Description

Python crashes, the code above works with numpy float32

Expected Behavior

Behavior with numpy:

>>> a = pd.Series([10.2, 100.2], dtype="float32")
>>> pd.to_datetime(a)
0   1970-01-01 00:00:00.000000010
1   1970-01-01 00:00:00.000000100
dtype: datetime64[ns]
>>>
