I'm seeing an LSM core dump derived from the WT-566 CONFIG:
############################################ # RUN PARAMETERS ############################################ # bitcnt not applicable to this run cache=94 compression=none data_extend=0 data_source=lsm delete_pct=14 dictionary=0 file_type=row-store huffman_key=0 huffman_value=0 insert_pct=40 internal_key_truncation=0 internal_page_max=14 key_gap=4 key_max=102 key_min=27 leaf_page_max=21 ops=382656 prefix=1 repeat_data_pct=37 reverse=0 rows=600 runs=0 split_pct=65 threads=10 value_max=1024 value_min=3 # wiredtiger_config not applicable to this run write_pct=5
The principal stack is:
(gdb) where

Another symptom that I see quite bit more frequently:
t, file:wt-000013.lsm, session.checkpoint: discarded page has hazard pointer: (0x807f93d00: ../src/btree/row_srch.c, line 220) t, file:wt-000013.lsm, cursor.search: ../src/btree/bt_page.c, 77: page != NULL && !WT_PAGE_IS_ROOT(page) t, file:wt-000013.lsm, cursor.search: aborting WiredTiger library
