For Complex factorizations QR,LQ,QL,RQ in Row Major, we use the corresponding transpose Col Major cases to process (LQ,QR,RQ,QL, respectively). The arithmetic of that demands the resultant TAU vector (of length min(M,N)) must be conjugated; i.e. all imaginary parts in the resultant TAU vector must be negated. The bug was reported by Kosaku Nagasaka on the developer's mailing list, verified by Anthony Castaldo and discussed with Clint Whaley.
