Clear errno before calling strtol() in spell.c. Per POSIX, a caller of strtol() that wishes to check for errors must set errno to 0 beforehand. Several places in spell.c neglected that, so that they risked delivering a false overflow error in case errno had been ERANGE already. Given the lack of field reports, this case may be unreachable at present --- but it's surely trouble waiting to happen, so fix it.
