Perl version: perl, v5.8.8 built for MSWin32-x86-multi-thread
OS: Microsoft Windows 2003 Server
Problem: crash using prDoc with some pdfs created with Xerox X-Solutions
ScanFlowStore
Solution: change xrefSection
move $buf contatination to beginning of while loop.
It looks like xrefSection is expecting a blank line which it can safely
ignore to follow the xref section before the trailer line, but the
ScanFlowStore software does not always include the blank line.
By moving the '$buf .=' line, the line used to break out of the xref
processing is scanned for the trailer information.
I have included a diff and a sample of the end of a pdf that causes a
problem.
Thank you
Steve Meister
