The problem is that you don't seem to understand how 1-bit bitmaps work. 
There are 8 pixels packed in each byte of monochrome bitmap data. Not 
only are you examining their values incorrectly, you are iterating far 
beyond the end of the bitmap buffer (at least 8 times too far), and 
furthermore you are ignoring the value of the bitmap pitch.

If you require help understanding how to process 1-bit-per-pixel 
bitmaps, I can possibly help you off-list, but this question is outside 
the scope of FreeType.
