      Description

      The PDF in question (on support drive) contains a compressed object stream which is technically malformed:

      bytes 7 0 5 136 4 194 3 243 9 275 10 323 1 330 2 420<</CreationDate<443A32303133303332363038333732392D303827303027>/Creator(HP Smart Document Scan Software 3.60)/Producer(OmniPageCSDK18)>><</Dest[1 0 R/XYZ 0 785 null]/Parent 4 0 R/Title(Page 1)>><</Count 1/First 5 0 R/Last 5 0 R/Type/Outlines>>[/PDF/Text/ImageB/ImageC/ImageI]<</ProcSet 3 0 R/XObject<</ImagePart_0 6 0 R>>>>[8 0 R]<</Contents 10 0 R/MediaBox[0 0 612 785]/Parent 2 0 R/Resources 9 0 R/Rotate 0/Type/Page>><</Count 1/Kids[1 0 R]/Type/Pages>>

      Our parser is expected a space between 420 and << and keeps on going until the next number is encountered and as a result reports in the incorrect byte offset for the object 2.

        ICEsoft Public SVN Repository #34508 Tue Apr 23 10:53:19 MDT 2013 patrick.corless PDF-572 added a parser tweak to make sure that the number parsing calls will return when a none digit is encountered and not just on whitespace.
