* After the file is generated, write bad offset values to

* the heap at 3 locations in the file:
|
|
* (A) Open the file:

* fd = HDopen(TESTFILE, O_RDWR, 0663);

|
* (B) Position the file at:
|
|
* (1) HDlseek(fd, 880, SEEK_SET);
|
|
* "/group1/group2": replace heap offset "8" by bad offset
|
|
* (2) HDlseek(fd, 1512, SEEK_SET);
|
|
* "/dsetA": replace name offset into private heap "72" by bad offset
|
|
* (3) HDlseek(fd, 1616, SEEK_SET);
|
|
* /soft_one: replace link value offset in the scratch pad "32" by bad offset
|
|
* (C) Write the bad offset value to the file for (1), (2) and (3):
|
|
* write(fd, &val, sizeof(val));

* Note: if the groups/datasets/symbolic links are changed in the file,
