APAR status

  • Closed as program error.

Error description

  • When compiling with optimization, code for a struct to struct
    move in a Metal C application is not generated.  For example,
    the struct to struct move:
    
       *struct1 = struct2.s;
    
    , may have code generated without optimization that may look
    like:
    
       LG    14,328(0,13)
       LG    14,@3886struct1@2343
       MVC   0(104,14),200(13)
    
    , but when optimization is enabled, these lines of code are
    removed from the output.
    

Local fix

  • Use a memcpy() call.
