Hi guys,

I had a rank-deficient matrix and I did a qr decomposition with pivoting. 
Since the Q matrix is orthogonal I did an At_mul_B of [:Q] and b - right 
hand side vector. And what I got were some weird results. When I was 
investigating this in the REPL I noticed that when I do transpose of the 
QRPackedQ I get the exact same matrix. Finally doing 
transpose(full(qr[:Q])) yielded the correct transposed matrix.

Can anyone confirm this as a bug?
