Sure, but this is not a compiler bug. The statement really is unreachable when PETSC_USE_ERRORCHECKING (default), but it can't be fixed without breaking a different configuration. It could be fixed in this case with more macros, but the problem is more general and we probably need to turn off some warnings.
