      It is possible to leave extra entries in the HS which makes verify trip. The reproducer repro.py works on this commit which is the latest on develop:

      commit bd267722770f832b80608f67ba8565a4141166da (HEAD -> develop, origin/develop, origin/HEAD)

      Do the following to repro:

      python3 ../test/suite/run.py -p hs34
cat WT_TEST/test_hs34.0/verify.err

      You should observe the following logs:

      wt, file:tablehs34.wt, verify hs: [WT_VERB_DEFAULT][ERROR]: int __hs_verify_id(WT_SESSION_IMPL *, WT_CURSOR *, WT_CURSOR_BTREE *, uint32_t), 80: the associated history store key a was not found in the data store file:tablehs34.wt: WT_PANIC: WiredTiger library panic
wt, file:tablehs34.wt, verify hs: [WT_VERB_DEFAULT][ERROR]: int __hs_verify_id(WT_SESSION_IMPL *, WT_CURSOR *, WT_CURSOR_BTREE *, uint32_t), 80: the process must exit and restart: WT_PANIC: WiredTiger library panic
