<p>That's what I did, I started the whole petsc config and build from scratch. The backtrace now says:</p>

As a first try, I've kept petsc-3.7.5 and only replaced superlu<br>
<br>
by the new xsdk-0.2.0-rc1 version. Unfortunately, this doesn't<br>
<br>
fix the problem, see the backtrace below.<br>

Fande,<br>

Perhaps the problem is related to petsc, not superlu?<br>
<br>
<br>
<br>
What really puzzles me is that everything was working fine with<br>
<br>
petsc-3.7.5 and superlu_dist_5.3.1, it only broke after we<br>
<br>
updated Scientific Linux 7. So this bug (in petsc or in superlu)<br>
<br>
was already there but somehow not triggered before the SL7<br>
<br>
update?<br>

<div>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. <br>
