Follow-up Comment #12, bug #57790 (project lwip):

Maybe the time is better invested debugging the error you have instead of
going to git head.

- What is the value of p or p->payload when it crashes?
- Are you sure threading requirements are met in your setup?
- Are you sure the STM MAC driver is not buggy?

I'm not aware of any problems here. Also, extended fuzzing tests did not show
such bugs (and they showed quite a lot, lately).
