Description

A unit test in our project is failing which is as below.

The query in question is 

SELECT * FROM tblspace1.t1 t10, tblspace1.t2 t20 WHERE t20.n1 = 3 AND t10.n1 = 3 AND t20.n1 = t10.n1

I get a stack overflow error-

LogicalProject(subset=[rel#19:Subset#4.ENUMERABLE.[]], k1=[$0], n1=[$1], s1=[$2], k2=[$3], n10=[$4], s2=[$5])
  LogicalFilter(subset=[rel#16:Subset#3.NONE.[]], condition=[AND(=($4, 3), =($1, 3), =($4, $1))])
    LogicalJoin(subset=[rel#14:Subset#2.NONE.[]], condition=[true], joinType=[inner])
      EnumerableTableScan(subset=[rel#11:Subset#0.ENUMERABLE.[]], table=[[tblspace1, t1]])
      EnumerableTableScan(subset=[rel#12:Subset#1.ENUMERABLE.[]], table=[[tblspace1, t2]])
