I couldn't reproduce exactly the same thing, but I did hammer away
randomly, including backspace a lot, with valgrind and triggered this
read that's past the end of a malloc'd area, so something's awry, and
probably what caused my earlier problem. See the first "26666" that's
part-way along the line; not the first word.

BTW, my Arch Linux is also up to date, so that helps remove one
variable. :-)
