Summary
I've got so far two sanitizer failures in __wt_lex_compare in my recent patch builds (in both cases, my changes are unrelated to the failure):
- An earlier failure: https://spruce.mongodb.com/task/wiredtiger_ubuntu2004_asan_unittest_test_patch_4ae81b794dc4a9229d94b2f70cf393287bda88c9_64ee453f3066157d889d7d0a_23_08_29_19_21_36/logs?execution=0
- One today: https://spruce.mongodb.com/task/wiredtiger_ubuntu2004_asan_unittest_test_patch_9989a9ee4b2e1cabec4ec1c8b927a5b295952459_64f0ba4cc9ec44321a55a7c6_23_08_31_16_05_33/logs?execution=0
Details
Here are the failure details from today's failure:
