I met errors and I don't know how to fix them,
https://gitlab.com/petsc/petsc/-/jobs/2151255655
The errors are all hypre-related.  @Stefano Zampini
<stefano.zamp...@gmail.com>  might know more.
Perhaps we can assert in MatHeaderMerge(A,C) and A does not contain
composed objects?  MatHeaderMerge() is so vague on what will be kept and
what will be discarded.
