            Description

            A client sent in a PDF http://www.pg.com/en_US/downloads/investors/annual_reports/2011/PG_2011_AnnualReport.pdf that has several page that don't render. The render failure is due to a parsing error in the Function 4 lexar (copy operator). One correct the PDF renders the missing content but there are numerous colour issues.

              A fix for this issue was accidentally check in for PDF-363. The lexer wasn't handling the 'copy' and 'if' operations. The 'copy' error was simply an index out of bounds issue, for lack of example. Similarly 'if' operators was correctly handling the expression but failed to put the expression back on the stack for evaluations.

              Once these two issue where fixed the pdf displayed the correct colour for the gradient in question.
