Runtime error calling DSYEV (eigenvalues)

[omuscato]

Hi, I am trying to call the routine dsyev in a simple case (as in LAPACK95 users' guide pag.120) but I get the runtime error

Illegal instruction (core dump)

The code is running on a IBM-BlueGene /Q , blas-2007 and lapack-3.4.1. Many thanks for any help !!!!!
