Not seen in pull-requests tests as the panic usually triggers after at least 20 iterations of the check-capture test (i.e. PR CI test is too short to capture this fail).

#9946 should fix this, merged, next daily test will tell
lyakh commentedon Apr 22, 2025
Haven't been able to find any more of these failures since #9946 was merged on Apr. 2nd. Propose to close

@kv2019i request for verification and close

Aa, sorry, I tried to close this already before, but hit a github glitch. So based on PR/daily test results, this issue is fixed and can be closed.
