#3116: boost GIL doesn't properly handle JPEG errors
-----------------------------------------------+----------------------------
 Reporter:  Giel van Schijndel <me@mortis.eu>  |       Owner:  hljin  
     Type:  Patches                            |      Status:  new    
Milestone:  Boost 1.40.0                       |   Component:  GIL    
  Version:  Boost 1.39.0                       |    Severity:  Problem
 Keywords:                                     |  
-----------------------------------------------+----------------------------
 When an error occurs during the decoding of a JPEG file (specifically its
 header) using jpeg_read_(dimensions|image|view) inside of libjpeg itself
 the program terminates.

 This is because libjpeg uses the `error_exit` handler from the current
 `jpeg_error_mgr` to signal an error. The default `error_exit` handler
 simply prints a message to stderr and calls `exit(EXIT_FAILURE)`. However,
 in order to properly handle this error one needs to override this
 `error_exit handler`. Attached patch does just that, using the same error
 message, though instead, it uses that message as a description for an
 `io_error(const char* desc)` generated exception
 (`std::ios_base::failure`).
