      Description

      I was trying to diagnose a hung wiredtiger-test-format-stress-sanitizer job on KodKod. I pointed GDB at the test format executable and it was able to get traces, but all of the variables were "optimized out". We need to work out why this happens specifically with wiredtiger-test-format-stress-sanitizer. I checked a wiredtiger-test-format-stress run at the same time on kodkod and it had the correct symbols, so it is likely something about the wiredtiger-test-format-stress-sanitizer job and potentially clang.

      An example backtrace from a thread
