assert_eq!(std::mem::size_of::<ScalarValue>(), 48);

the result is 64. I am not sure which should be the case.

This doesn't happen for me. How can we reproduce it?

https://github.com/apache/arrow-datafusion/blob/01d7dbaf392b4a217e1a27c96bbcd1126b763828/datafusion/common/src/scalar.rs#L4637-L4646

Maybe it is related to architecture?

It seems so, also in CI there is no problem. I use Macbook M1-Ventura 13.3.1

Maybe we should just conditionalize the test (like #cfg(...)) for architectures where the size is different -- I thought I remember this test having a aarch variant that asserted the size was 64 for some reason

I will do so, thanks @alamb .
