Strange EOF happenings

For some reason, whenever the program reads 1A in hex, 26 in dec it is reading it as EOF. I have it print out the character and, sure enough, it prints -1. I don't get it. Other programs are detecting EOF just fine. Here's the culprit code:

Code:

---

new_byte = fgetc(_source);
  while(new_byte != EOF){
      decompress(new_byte, bit);
      for(i=0; i < (8/bit); i++){
        fputc(_new_pixels[i], _dest);
      }
      printf("%d: ", j);
      j++;
      new_byte = fgetc(_source);
      printf("%d\n", new_byte);
  }

---

That is supposed to loop through over 8000 times, but it gets to byte number 206 and hit EOF. Here's the end of the output:

Code:

---

200: 0
201: 0
202: 15
203: 255
204: 139
205: 47
206: -1

---

Byte number 206 is 26, not -1

I changed byte 206 to 27, then it stopped on the next 26 later in the file.

Any ideas?
Thanks

Is new_byte an int like it should be?

Yes sir.

Would something like this produce any clues?

Code:

---

  new_byte = fgetc(_source);
  while ( new_byte != EOF ) {
/*
      decompress(new_byte, bit);
      for(i=0; i < (8/bit); i++){
        fputc(_new_pixels[i], _dest);
      }
*/
      printf("%d: ", j);
      j++;
      new_byte = fgetc(_source);
      printf("%d\n", new_byte);
  }
  if(ferror(_source))
  {
      perror("_source");
  }
  if(feof(_source))
  {
      puts("Yup. EOF");
  }

Code:

---

200: 0
201: 0
202: 15
203: 255
204: 139
205: 47
206: -1
Yup. EOF

That's interesting. By the way, the source file is 8196 bytes.

It only does that in Windows. I compile and run it on UNIX over ssh and it works fine. But it is going to be graded on a Windows machine. Maybe I'll just do it in UNIX and make a note of the problem.

Here's the end of execution in UNIX:

Code:

---

8192: 0
8193: 0
8194: 0
8195: 0
8196: 0
8197: -1
Yup. EOF

I don't seem to be all that helpful here. One more try: is _source opened in binary mode?

HOLY CRAP!! That worked.

Thanks a million Dave.
