Making minimal changes to your code to allow it compile here, and it simply never finds anything(very quickly), no matter how simple I make the search criteria:

I've wasted enough time on it; and won't be expending any more, but here is the modified code that compiles clean (apart from warnings that originate from your posted code):

I'd suggest you enter it in an obfuscated C competition; could be a winner.
