it seems the author has not considered large files.
eg. FileSize returns:
 static_cast<int>(f.tellg() - begin_pos);
ie. an int

i think you'll need to do quite a few fixes for this,
and i'm not even sure you can make ifstream use
large files...

and this comment:
/**
* load entire file into buffer
*/

on the next function implies that you are going to need >4G RAM anyway...
(which, i suppose, you may have)

sorry i can't be of more help -- got to go to lunch.
