Nice catch, will check the return value of "strdup".
For input_name mem leak, in some cases the input_name can't be called
with free(), like those got from parse "-i" option. In case the old
input_name is got from malloc through strdup, I think it's not a big
issue given that buffer will be freed any way when the application exit.
