Reproducing #27666

Hi All! I’ve tried to reproduce #27666 problem but the test from commit 0aabf51 passes on all branches.

Is something wrong with me or with the test?

Installation details
#ScyllaDB version:
#Cluster size:
os (UBUNTU):

I could confirm: I tried to reproduce this problem too (to check it really fixed for my version), using test_repair_sigsegv_with_diff_shard_count - expected to be a problem reproducer but this test never fails for any previous version. It there any other way to reproduce it?
