Enabling heuristic optimization

[niceIrene]

According to this paper: Provenance-aware Query Optimization
Heuristic optimization is important in improving the performance of TPC-H queries. I tried to enable it by setting this parameter as True:
-heuristic_opt DEFAULT VALUE: FALSE ACTUAL VALUE: FALSE
Activate heuristic relational algebra optimization
However, it gave the following error, which looks like operators in the queries such as sum(l_extendedprice * (1 - l_discount)) caused the error.

ERROR (exception.c:145) exception was thrown (RECOVERABLE) operator_optimizer.c - 143 - <failed assertion: checkModel((QueryOperator *) rewrittenTree)

Error occured
(operator_optimizer.c:143)
failed assertion: checkModel((QueryOperator *) rewrittenTree)
