I could not reproduce this. There was no crash at the end of the test run, there is error print that says
[00:00:10.215,052] <err> net_conn: Address families different but no crashes.
The head of my git tree was b17d9ee
I am using SDK 0.9.5 so the qemu version is most probably different which could explain the different result.

I tried this today in my environment.

Test is successful with below messages at the end of test.
PROJECT EXECUTION SUCCESSFUL
[00:00:02.540,000] net_conn: Address families different

OS: Ubuntu 18.04
Toolchain: Zephyr
SDK: zephyr-sdk-0.10.0-rc3
git head: rveerama1@2384ebc

I didn't see any crash.

Also fyi, #14069 has a patch for TCP tests are migrated to new net_pkt api.

Also fyi, #14069 has a patch for TCP tests are migrated to new net_pkt api.

PR merged and I tried it with today latest rveerama1@7967829.

Hence closing this issue, re-open if you still find it.
