as it was not as clear as possible in the first message, I want to clarify 
that the problem is in saving a modified file incrementally by giving  
writeForceIncremental flag to PDFDoc->saveAs. The problem occurs only if the 
file is linearized.

I attached a patch, which modifies the original behaviour of getStartXRef for 
the case that the file is linearized. With the patch applied my application 
modifies the file okay.

I also attached the original (test2.pdf) and modified files before and after 
applying the patch, respectively.

openTest.pl uses CAM::PDF and demonstate my problem. It opens test2.pdf and 
test2-afterPatch.pdf okay but not test2-beforePatch.pdf

If I could assist you any further don't hesitate to contact me.
