MKL PARDISO: floating-point error with zero pivots ...

Hi,

we have detected problems with the current version of the PARDISO solver.

(MKL vers. 2017.4.210, Windows x64 architecture, static linking, Microsoft VS 2015).

PARDISO produces a floating-point error in phase 22, if the coefficient matrix of a FEM analysis has zero pivots.

Another problem is, that PARDISO doesn’t return the correct line number of the first pivot element (iparm[29]).

In former versions PARDISO worked well in this regard.

I have attached some screen shots and a code sample to demonstrate the above problems.

Thank you for your answer.
