To Reproduce

https://github.com/apache/arrow-rs/runs/6867357727?check_suite_focus=true#step:4:1630

or running cargo +nightly miri test -p arrow -- --skip csv --skip ipc --skip json -- locally

Steps to reproduce the behavior:

Expected behavior

No leaks being reported

Additional context

If this is actually expected behavior we might want to run ffi tests separately with leak reporting disabled.
