One of our tests wasn't passing and we were debugging and
|
|
debugging only to be left scratching our heads.
|
|
|
|
It turns out that labels in RDATA are terminated by RLENGTH,
|
|
not by null (as most labels are), but since generally CLASS
|
|
begins with 0x0001, which looks like a null terminator... in
|
|
almost every case, it tooks us forever to figure it out.
