[petsc-dev] KSP accepts mismatched sizes between Mat and PC

[Alp Dener]

Hi Barry,

While I was working on some active-set related stuff in TAO, I discovered
that I can call KSPSetOperators() with differently sized Mat and PC objects
without getting any errors or warnings about the size mismatch. Note that
my Mat object is explicit, but the PC object is a MATSHELL. Is this
intended behavior, or is it a bug?
