Ingo Bürk commented on FLINK-24480:
-----------------------------------
I can reproduce this locally (even on master) by running the test with
-Xss228k, which shows that it is indeed related to the stack size. I _think_
the reason it only fails on 1.12 / 1.13 might be due to the new code split
infrastructure. Reducing the number of fields as I did in the PR does allow the
test to pass again.
