      Non-ASAN builds produce the "out of memory" error:

      A slightly different query produces just ASAN error, without OOM:

      CREATE TABLE t1 (a INT);
      INSERT INTO t1 VALUES (1),(2);
      SELECT DISTINCT VARIANCE(1) FROM t1 GROUP BY a, ExtractValue( 'foo', 'bar' ) ORDER BY BENCHMARK( 4, VAR_SAMP( a ) );
