483     CHKERRQ(ierr) is fundamentally a macro replacement for

485 
486     Although typical usage resembles "void CHKERRQ(PetscErrorCode)" as described above, for certain uses it is
487     highly inappropriate to use it in this manner as it invokes return(PetscErrorCode). In particular,
488     it cannot be used in functions which return(void) or any other datatype.  In these types of functions,
489     you can use CHKERRV() which returns without an error code (bad idea since the error is ignored or
490          if (ierr) {PetscError(....); return(YourReturnType);}
491     where you may pass back a NULL to indicate an error. You can also call CHKERRABORT(comm,n) to have
