A mongo sanitizer test hit a LeakSanitizer: detected memory leaks error after switching to a new build variant that now includes an address sanitizer. The leak appears in the load command when using the wt utility.
The call stack from the sanitizer in the BF:

I've been able to reproduce a similar sanitizer error when running wt load on an example database from test/format after building with the cmake flag -DCMAKE_BUILD_TYPE=ASan.
