Hi Pavel and Hillf,

I believe there's a little misunderstanding, apologies. The reproducer
does not trigger the bug on the for-next tree which has patches for
5.13. The reproducer process exits correctly. Likely one of those
commits that will be back-ported to 5.12 will address this issue.
When I wrote `the reproducer fails`, I meant to indicate that the bug
is not triggered on for-next. I will word it better next time!
