      Work Description: wenjun-zhu commented on pull request #1782: [TRAFODION-3264] eliminate unneeded function call in Lob-related functions
URL: https://github.com/apache/trafodion/pull/1782
 
 
   in file core/sql/executor/ExExeUtilLoad.cpp, lines like:
   ```
   	    ex_expr::exp_return_type exprRetCode =	
   	      lobTdb().inputExpr_->eval(NULL, 	
   					workAtp_);
   ```
   call function eval(), with first parameter NULL.
   
   Then code in ex_expr::evalClauses() accesses NULL pointer, so the server aborts.
   
   As @sandhyasun said, this invocation is unneeded, so remove these code.

> this calls eval() function with 1st parametere NULL.
> When PCode is off, it would access null pointer in function ex_expr::evalClauses(), and then abort.
