Another point I need to mention is that I had the same problem when as my 
first try of parallelization, I paralleled a much simpler code, the 
step-25, based on the step-40 . 
I received the same Segmentation Violation error from Petsc. At that time, 
I replaced PreconditionerAMG with PreconditionerJacobi and the problem 

However, Now even using PreconditionerJacobi can not remedy the issue even 
if it works for very few initial value and boundary conditions.
