Bug#945188: xpdf: memory leak when changing page
Package: xpdf
Version: 3.04-13
Severity: important
When one changes the displayed page (e.g. with PageDown or PageUp),
xpdf takes more memory, even if the page has already been displayed
(thus this is not due to caching).
For instance, consider /usr/share/pari/doc/users.pdf from pari-doc.
It starts with 32 MB. And each time I do a PageDown or PageUp, it
takes an additional 16 MB.
One can easily end up filling the memory of the machine. This happened
to me several times, with my machine completely freezing for several
minutes, until I found out that xpdf was the main cause.
