[petsc-users] petsc code crash on AIX with POE

[Satish Balay]

Perhaps you can build with --with-debugging=1 - and get a proper stack
trace with the debugger? [use a different PETSC_ARCH for this build -
so that the current optimzed build is untouched.]

Also - does sequential run with mpcc_r work?
