Suspicious Optimization Behavior - LNK2019 inline virtual destructors

Hi I am experience some strange behavior when turning on optimization (/O1 and above). On linking phase, inlined virtual destructors of base abstract classes are unresolved. I am using Intel 2017.0.109 on Windows10 64bit with Visual Studio 2013. Intel compiler 2016.3.207 has the same behavior, however when compiling with Visual Studio, I do not get these errors.

Pardiso crashes in 2017 MKL only when OMP_NUM_THREADS=2

I have a small matrix that consistently causes pardiso to crash only when I use OMP_NUM_THREADS=2 or 3. My machine has 12 cpus and any other setting for OMP_NUM_THREADS works.

MKL ?trexc function

Good day to all.

I am a student. I'm doing matrix calculations.

There was a problem with using the ?trexc function of MKL that makes the reordering of Schur factorization
