Dear Sir,

I have used ppl 0.9 in my project, now I am upgrading it to ppl 1.1, during compilation I had ppl interface issue i.e. shrink_bounding_box and some other functions not found. I have commented all these functions and compiled my project successfully, now when I try to parse some file it returns me the following error: 

terminate called after throwing an instance of 'std::out_of_range'
  what():  basic_string::substr
Aborted

I want guidelines and will be glade to have you positive response.  

Best Regards,
Syed Sabah-ud-din Gilani
