Facing error when running PARDISO at phase11

Hi,

I am coding with Fortran 90 in Microsoft VS2008. In order to solve a sparse matrix, the PARDISO solver in MKL has been used. The matrix to be solved is a complex number one.

When I tried to run the solver under, it stopped at phase=11 due to an error as following:

"Access violation writing location 0xcdcdcdd5."

The disassembly is stopped at subroutine _mkl_pds_metis_pqueueupdateup of MKL.

Could anybody suggests about what could be the possible reason for such an error? 

Thank you!
