Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When compiling using the IBM z/OS XL * * C/C++ compiler V2R1 or higher, warning * * message "CCN3726 Attempting to pop an * * empty pack stack. Current pack may * * change" may be issued. * **************************************************************** * RECOMMENDATION: * **************************************************************** In z/OS V2R1, the z/OS XL C/C++ compiler introduced an additional warning message when more than one "#pragma pack(reset)" statement is found in sequence without a corresponding "#pragma pack(packed)" statement. Earlier versions of the z/OS XL C/C++ compiler would silently tolerate extraneous "#pragma pack" statements. As the IBM WebSphere MQ for z/OS CSQDSMFC.H header file contains an extraneous "#pragma pack" statement, attempting to compile a C program that includes the CSQDSMFC.H header file can result in a CCN3726 warning message being issued and compilation may return a non-zero RC.
Problem conclusion
The extraneous "#pragma pack(reset)" statement has been removed from the CSQDSMFC.H header file. 100Y CSQDSMFC
