The png library uses setjmp/longjmp to throw exceptions when reading. If this is not set up, the png library calls abort(). This change handles the errors and throws a C++ exception instead. This issue was found by testing images from pngsuite at http://www.schaik.com/pngsuite/. These images are included and a unit test was added to test both images that should be successful and images that should throw an exception.
