Fande,
That's what I did, I started the whole petsc config and build from scratch. The backtrace now says: /home/cklaij/ReFRESCO/Dev/trunk/Libs/install/Linux-x86_64-Intel/superlu_dist-xsdk-0.2.0-rc1/SRC/mc64ad_dist.c:2322 instead of the old: /home/cklaij/ReFRESCO/Dev/trunk/Libs/install/Linux-x86_64-Intel/SuperLU_DIST_5.1.3/SRC/mc64ad_dist.c:2322 which doesn't exist anymore.

Unfortunately, this doesn't fix the problem, see the backtrace below. Fande, Perhaps the problem is related to petsc, not superlu? What really puzzles me is that everything was working fine with petsc-3.7.5 and superlu_dist_5.3.1, it only broke after we updated Scientific Linux 7. So this bug (in petsc or in superlu) was already there but somehow not triggered before the SL7 update? Chris I do not know how you installed PETSc. It looks like you are keeping using the old superlu_dist. You have to delete the old package, and start from the scratch. PETSc does not automatically clean the old one. For me, I just simply "rm -rf $PETSC_ARCH" every time before I reinstall a new PETSc. Fande,
