Alessandro Molina commented on ARROW-11751:
-------------------------------------------

This seems now to be invalid
{code:java}
>>> pyarrow.scalar("foo") == None
False {code}

>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: Python
>    Affects Versions: 3.0.0
>         Environment: OS X/ py 3.8.5 / pa 3.0.0
>            Reporter: Ben Schmidt
>            Priority: Minor

> When attempting to test equality of a pa.scalar to the value None in pyarrow, I receive a bus error and the process exits entirely. Carries for both string and numeric scalars, but otherwise no idea of the cause, solution, or scope, just reporting. Present on two different machines. Happy to give more details if the code below is not reproducible.  
>  
> {code:java}
> import pyarrow as pa
> g = pa.scalar("foo")
> g == None{code}
> {code:java}
> # WITH OUTPUT:
> Python 3.8.5 (default, Sep  4 2020, 02:22:02) 
> [Clang 10.0.0 ] :: Anaconda, Inc. on darwin
> Type "help", "copyright", "credits" or "license" for more information.
> >>> import pyarrow as pa
> >>> pa.__version__
> '3.0.0'
> >>> g = pa.scalar("foo")
> >>> g == None
> [1]    25176 bus error  python
> {code}
