Description

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.  

 

import pyarrow as pa
g = pa.scalar("foo")
g == None
