Bug in MKL PZHEEVD?

When diagonalizing a Hermitian matrix using MKL's pzheedv I get wrong eigenvalues. I am using the MKL version that ships withcomposerxe-2011.3.174 for LINUX.

With other math libraries I get the correct result.

Has this been previously reported as a bug? Is this fixed in a recent version? Which version would this be?

Thank you very much in advance.

Kind regards,
M.

Give details of your example, unless you claim that pzheedv gives wrong eigenvalues all the time.

Many claims of MKL giving wrong results have been found to be related to calling MKL incorrectly.
