Good you mention these. I checked my GerH sources as well to make sure
I don't screw up the answer:


The divisions by zero are 'by design'. I wouldn't call them 'normal'
so I immediately recognized them, but they are a way to create 'NaN's
which are useful to mark certain math operations as 'undoable' in the
crm R-domain math context (square roots of negative values, that sort
of stuff).

The 'subscript out of range' is definitely a bug as it has been
corrected long ago in the GerH code: snippet follows:

---
    {
        char vname[129];
        strncpy(vname, &nametext[namestart],
                ((128 < namelen) ? 128 : namelen));
        vname[128] = 0; /* [i_a] boundary bug */
        fatalerror("You have blown the memory-storage gaskets while trying"
                   "to store the ISOLATEd variable ", vname);
        return 1;
    }
---


I hope Bill will correct the latter in the official wget, please?
