Bug in the source code

[gogo9th]

Hi,

Thanks for your useful compression code. I found there is a bug in here. The line: for(temp_pointer_length = 0; && uncompressed_text[look_ahead++] == uncompressed_text[look_behind++]; ++temp_pointer_length)

Should be changed to: for(temp_pointer_length = 0; look_ahead < uncompressed_size && uncompressed_text[look_ahead++] == uncompressed_text[look_behind++]; ++temp_pointer_length)

Basically, we should check the array boundary: "look_ahead < uncompressed_size"
