Bug in dsyev row-major

Hello, 

When I compile and run the MKL examples `lapacke_dsyev_row.c` I get the following output: 

LAPACKE_dsyev (row-major, high-level) Example Program Results

 Eigenvalues
 -11.07  -6.23   0.86   8.87  16.09

 Eigenvectors (stored columnwise)
  -0.30  -0.61   0.40  -0.37   0.49
   0.00  -0.29  -0.41  -0.36  -0.61
   0.00   0.00  -0.66   0.50   0.40
   0.00   0.00   0.00   0.62  -0.46
   0.00   0.00   0.00   0.00   0.16

The lower part of the matrix is missing. 

This looks like a bug, is it the right place to report it ? 

It seems that the row  col major version is working. 

This happens with the version "2019.3.199" on both linux and windows.

Sincerely, 

Marc Lasson.
