You are right, there is a bug in res_querydomain, Line 737 *(ptr++ - 1) = '.'; should be *ptr++ = '.'; I would also add a debug printf at the top of the function: DPRINTF(statp->options & RES_DEBUG, "querydomain \"%s\" \"%s\" type %d\n", Name, DomName, Type); Unfortunately I am not setup to build Cygwin so I can't test the above nor submit a proper patch.
