Follow-up Comment #5, bug #57377 (project lwip):

> Did I miss something or did some other fuzz setting change?
As far as I know, my test driver is merged, refactored, and improved by Simon
(@goldsimon). As a result of the process of them, some crashes I reported seem
to become unreproducible.

As Erik (@yarrick) written, LWIP_RAND_FOR_FUZZ seems to make them
unreproducible. Local ports of TCP/UDP clients depend on LWIP_RAND(), and in
the crashed test cases these numbers are hard-coded (TCP: 58311, UDP: 50536).
As LWIP_RAND_FOR_FUZZ allows to override LWIP_RAND(), I think this may be why
the crashes have become unreproducible.
