tests/lwip_sock_ip: failing on native when using IPV4 #17144
Description
Description
Testing #17115 I discovered that there seems to be some unsafe access somewhere in LWIP when using IPV4.
Bisecting leads to #16259, but that PR introduces mechanisms to identify unsafe code so it might be that it's just since that PR that we have the tools to identify an underlying issue.
Steps to reproduce the issue
LWIP_IPV6=0 LWIP_IPV4=1 make -C tests/lwip_sock_ip/ clean flash test -j
or
LWIP_IPV6=0 LWIP_IPV4=1 make -C tests/lwip_sock_udp/ clean flash test -j
Expected results
