The issue can be reproduced by applying the following patch:

And then by running the following command:
> ~/wiredtiger/build/test/cppsuite$ ./run -t base_test -l 2
You should see the following output:
run: FAILED: bool test_harness::postrun_statistic_check::check_stat(test_harness::scoped_cursor&, const test_harness::postrun_statistic_check::postrun_statistic&) const/214: cursor.get() != nullptr run: process aborting WiredTiger Error: aborting WiredTiger library Aborted (core dumped)
The crash occurs when the runtime monitor component is executing its {{}}finish function:
void
runtime_monitor::finish()
{
_postrun_stats.check(_cursor);
component::finish();
}
The _cursor variable is initialized only if the component is enabled in the load function.
The fix should be straightforward:
