Crash while copying PDF with annotations

[neklesayurii]

Hello

Lib crashes when I try to copy this original.pdf PDF. It happens in destructor on delete[] mXrefTable; step.

I found that issue is hidden in PDFParser::BuildXrefTableFromTable() function, because if(extendedTable) is triggered twice. And when it is triggered second time extendedTable is equal to mXrefTable.
To avoid crash I added equality check if(extendedTable && extendedTable != mXrefTable). But still annotations does not get copied (I refered to CopyingPagesWithComments.cpp sample).

After resave in Foxit Reader PDF resaved.pdf CopyingPagesWithComments.cpp sample works without problems.

Does anyone know how to solve the problem with original pdf?
