Bug Description

Binary package hint: cups

pdftopdf reaches 2GB (!) memory consumption when I try to print pdf documents with option 'multiple pages per sheet' enabled. It eventually succeeds, but swapping takes minutes, slowing any application down, and will fail on computers with less RAM.

Further notes:
- My printer is a HP DSC750
- Printing was started from evince
- Page ranges were also specified
- Ubuntu Karmic, generic kernel
- cups package up-to-date

  * debian/local/filters/pdf-filters/filter/texttopdf.c: Workaround for
    bug in ttf-freefont which messed up the output of the texttopdf filter.
    Thanks to Hin-Tak Leung and Steve White to find this solution (LP: #447961).

    fix from Koji Otani for the following: (1) Fixed some memory leak;
    (2) pdftopdf now delays fetching a referenced object until when it is
    written to the output. This fixes memory hogging with N-up output
    (N pages per sheet). The fix is mainly done by (2). This fixes
    LP: #508731.
