SQL & PL/SQL :: ORA-06552 / Compilation Unit Analysis Terminated

The following error has occurred:

ORA-06550: line 26, column 30:
PL/SQL: ORA-06552: PL/SQL: Compilation unit analysis terminated
ORA-06553: PLS-320: the declaration of the type of this expression is incomplete or malformed
ORA-06550: line 7, column 6:
PL/SQL: SQL Statement ignored

I am getting the error when i run the below anonymous block. Historic_report_data has got plenty of columns and using only the columns that are in tb_Statement in the query. It is working fine if i use a table with same number of columns as tb_statement instead of historic_report_data.

DECLARE
v_cnt NUMBER:=0;
v_data_load_error EXCEPTION;
BEGIN
dbms_output.put_line('Reconciliation scripts');
dbms_output.put_line('Reconcile tb_bank_Account_month and report_hist_data');

[code]....
