This bug is indeed inside of superlu_dist, and we started having this issue
from PETSc-3.6.x. I think superlu_dist developers should have fixed this
bug. We forgot to update superlu_dist??  This is not a thing users could
debug and fix.

I have many people in INL suffering from this issue, and they have to stay
with PETSc-3.5.4 to use superlu_dist.
