Major - P3 Test run
http://build.wiredtiger.com:8080/job/wiredtiger-test-format-stress-sanitizer/16060/console
I have run the config in question on my linux machine against revision 9494eb2899e010c378f882348ff3b58d37ecab08 and was able to reproduce the issue.
From reading, it appears that we are performing a __wt_session_copy_values operation without a txn set as part of a cursor modify operation via row_modify in format.
