I recommend that to stop the crack from continuing to grow, you drill a small hole at either extreme end to increase the surface area over which the stress is exerted. Standard machine shop practice.

PS - the larger the whole you drill, the greater area the stress will be spread over and the better the chance that the crack will not propogate. If you wish, rather than rely on filler, you could then thread the hole with a pipe tap, thread in a pipe plug, and dress off the surface flush.
