[petsc-users] where is PCREDISTRIBUTE?

[Barry Smith]

   Sorry, there was an error in the case when the preconditioner was  
rebuilt with the same nonzero pattern, an internal matrix was  
mistakenly freed early.

    Drop the attached src/ksp/ps/impls/redistribute.c  and run make in  
that directory and it should run correctly.
