[petsc-dev] METIS update -> MUMPS crash

[Garth N. Wells]

I've been having trouble with MUMPS crashing since METIS was recently updated in

    https://bitbucket.org/petsc/petsc/commits/67125ba

The problem does not appear for very small problems, but for other
problems it does. I can reproduce a crash with ex55
(src/ksp/ksp/examples/tutorials/ex55.c):

    ./ex55 -ksp_type preonly -pc_type lu -pc_factor_mat_solver_package
mumps -ksp_view -ne 128

For 'ne' less than about 50 it runs fine but crashes for anything
bigger. Changing the LU solver to another package it runs fine.
Backtrace below. The message

    http://www.mail-archive.com/petsc-users@mcs.anl.gov/msg17695.html

looks to be related.
