I did some quick and dirty debugging, and after a few iterations of the
main loop, the segfault is triggered in this section of code:

      for(j = i + 1; qu[j] != -1; j++)
        wt[qu[j]]++;

j ends up with values greater than 14, which makes it run off the end of
the qu array and eventually you end up trying to access a random element
of wt, whiuch causes a segfault.

This is happening because there isn't a -1 in the qu array where you
expected there to be.

I don't know why *that* is happening, but I figured I'd leave something
for you to solve.  :-)
