[petsc-dev] partitioning error

[Mark F. Adams]

This  'make runex56' with:

~/Codes/petsc-dev/src/ksp/ksp/examples/tutorials>cat .petscrc 
-pc_gamg_repartition true

Appended is one procs error messages.

As I said this does run on the Cray but I have not updated metis on Cray so I suppose it could be a new bug or an architecture specific bug.

BTW, I have an application that fails in repartitioning (different looking error) but I have not been able to reproduce the problem with PETSc tests.
