[petsc-users] seg fault with superlu

[Balay, Satish]

Don't remember - but you can try with latest superlu_dist and see if
the problem persists. [it has a bunch of fixes]

To try latest superlu_dist - you can use balay/update-superlu_dist_6.1.0/maint_no_merge

[this branch is off maint - so to try with master - you can merge this with master]

git checkout master
git checkout -b test
git merge origin/balay/update-superlu_dist_6.1.0/maint_no_merge
