[petsc-dev] Assertion at agg.c:514 tripped

[Jed Brown]

Mark, in a nonsymmetric (but structurally symmetric) bs=2 problem from
Lulu, we are tripping this assertion.

          else{            /* I'm stealing this local, owned by a ghost */
            assert(sgid==-1);


What does this mean? Can't we at least always use SETERRQ for errors?


Also from that section of code, I notice you are using PETSC_ERR_LIB for
internal PETSc logic/corruption errors. They look like they should be
PETSC_ERR_PLIB.
