It looks like you're fixing multiple separate bugs in a single patch,
which makes it really difficult to understand. You're also not
describing what the issues are, and why the changes you're proposing
are fixing those bugs.

Do you have reproducers for those bugs? That would be helpful, as I've
never seen the panics/leaks/checksum issues you're mentioning.

Please fix only one issue per patch. Otherwise, it's really hard to
tell what change fixes which issue.

Thanks,
