hmm - but the most likely cause of a failure at the indicated point
(other than bad object code, e.g., from some versions of gcc), is
a problem allocating the 'pairs' array.  I'd check/see if it was
a null pointer, etc., with the debugger.  Other than that, an
out-of-range value for its subscript seemed a good guess.
