No, it does not happen there, because filevec|cmp|curr is not changed. The function reads the component changed but does not write back. It just wastes time? I cannot see that the function's results are saved anywhere and are used somewhere else…

The following function called from diff_2_files() is already build_script() from type declaration of struct change *script. Before, I found that build_script() already uses faulty data, so it's compareseq (), the function that gets called before build_script() and shift_boundaries(), that creates the faulty data values?
