Well, up to an error in the testing routines, at least.

TESTING/LIN/sdrvls.f has

       REAL, ALLOCATABLE :: WORK (:)
...

       REAL               RESULT( NTESTS ), WQ

and calls

                               CALL SGELS( TRANS, M, N, NRHS, A, LDA,
      $                                    B, LDB, WQ, -1, INFO )

[...]

                               CALL SGELS( TRANS, M, N, NRHS, A, LDA, B,
      $                                    LDB, WORK, LWORK, INFO )

so that one really is illegal and should be flagged.
