Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The DSECT utility C struct output is incorrect in 2 scenarios.
  
  
  
     === TEST CASE 1 ===
  TEST       DSECT
  FIELD1     DS    AL1
  VARDATA    DS    0CL128
             END
  
  Actual output:
  
  struct test {
    unsigned char  field1;
    __extension__ unsigned char  vardata[128];
    };                         // Incorrect struct size
  
  Expected output:
  
  struct test {
    unsigned char  field1;
    __extension__ union {
      unsigned char  _vardata[128];
      } _test_union1[0];
    };
  
  
  
     === TEST CASE 2 ===
  TEST       DSECT
  FIELD1     DS    AL1
  ALIGN      DS    0F
  FIELD2     DS    C
             END
  
  Actual output:
  
  struct test {
    unsigned char  field1;
    unsigned char  _filler1[3];
    struct {
      unsigned char  _field2;
      unsigned char  _filler2[3];
      } align;
    };
  
  Expected output:
  
  struct test {
    unsigned char  field1;
    unsigned char  _filler1[3];
    union {
      __extension__ int      _align[0];
      unsigned char  _field2;
      } _test_union1;
    };
