Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling and * * running a COBOL program that contains either * * of the following: 1. a comparison of a UTF-8 * * literal with a non-UTF-8 data item; or 2. a * * move of a UTF-8 ALL literal into a non-UTF-8 * * data item. * **************************************************************** * PROBLEM DESCRIPTION: 1. For comparisons, compiler abort * * with message: * * * * IGYPG5306-U An internal compiler error * * occurred. Condition (F) failed at * * IGYPCXU-32770-IGYZCNUL: expected * * alphanum * * * * 2. For ALL literal moves, incorrect * * runtime results. The ALL literal * * value is not repeated in the * * receiver. * **************************************************************** * RECOMMENDATION: Apply the IBM-provided PTF. * **************************************************************** Incorrect code was being generated for comparisons of UTF-8 literals with non-UTF-8 data items. For the move of a UTF-8 ALL literal to a non-UTF-8 data item, the ALL status of the literal was inadvertently being lost during the conversion of the literal to the target codepage during the move.
Problem conclusion
The compiler was updated to ensure UTF-8 literals can be correctly used with non-UTF-8 data items in both MOVE and compare operations.
