Only of the 32bit rawhide builds ? [as 32bit ones  one f24, epel were fine?]

This is very puzzling to me.

This points to 'ierr = MPI_Comm_rank(PETSC_COMM_WORLD,&rank);CHKERRQ(ierr);'

So somehow suggesting the wrong MPI [include or library] is getting used by the test code.

But only for these 2 tests - in this one build? Thats weird..

I was hoping valgrind would help figure out this [perhaps point to
wrong library in runtime load - or something]..
