----------------------------------

                 Key: TEIID-582
                 URL: https://jira.jboss.org/jira/browse/TEIID-582
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 6.1.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Critical
             Fix For: 6.1.0

we are not careful about ensuring that that every symbol is unique in a plan, there's a chance mapping the expression in an aggregate (i.e. sum(x) -> sum(sum(x))) in a project node will cause the same symbol to be updated in a sort node.  Then mapping the sort node would create a recursive aggregate symbol.
