I cannot reproduce this segfault. why are you looking for string distance in two binary files?
string distance is an algorithm that aims to work on textual contexts. Can you provide a backtrace with symbols? Can you upload those files somewhere, so I can reproduce it? Or prepare a simpler test case? Thanks!
