Comment 19 for bug 1920190

@Till, thanks for the heads-up. pdftoraster is the one that came installed automatically, I didn't install anything manually.
(manu@lari:~$ dpkg -S /usr/lib/cups/filter/pdftoraster
cups-filters-core-drivers: /usr/lib/cups/filter/pdftoraster)

@Pratyush, 30% of 4GB is around 1.3GB, which is close to what I'm seeing for the 12-page file as well (I see 1.8GB).

But then memory grows approximately linearly with the number of pages, which is why I think either a memory leak or at the very least bad design in pdftoraster must be involved, although that might not be the only bug.

Is this the right upstream repo for pdftoraster as shipped through the cups-filters package?:
