Hi!

I have seen this problem before. Back then, the person that tried
to use ftpupload.c to upload a file didn't check that the file
could be opened locally:

  hd_src = fopen(LOCAL_FILE, "rb");

Are you really sure that this fopen() is successful?

You should check the file handle afterwards:

  if(!hd_src) {
    fprintf(stderr, "Couldn't open %s\n", LOCAL_FILE);
    exit(1);
  }

If you don't do this, you might pass an invalid file handle to
curl, and you will get a violation of some kind.

(BTW, this check is intentionally left out of the example code
to make it easier to read.)
