DftiCommitDescriptor hangs my application

Hi,

I've been struggling with this for a while, hope you can help.

I'm creating a shared library on Linux (Centos 6.7) using FFT's implemented with the MKL. My library works fine when used together with my own test program, but fails when used from a 3rd party application.

The problem has been pinned down to the FFT's. Print-output arrives on screen after calling DftiCreateDescriptor and DftiSetValue, and the status is 0. But when I subsequently call DftiCommitDescriptor the 3rd party application keeps running at 100% cpu and doesn't show any print-output anymore.

Computes all eigenvalues and, optionally, eigenvectors of a real symmetric matrix in packed storage.

?sygvd

Computes all eigenvalues and, optionally, eigenvectors of a real generalized symmetric definite eigenproblem using a divide and conquer method.
