[poppler] [PATCH 0/5] *** SUBJECT HERE ***

[David Benjamin]

So, bug #24575 had a patch sent in that partially fixed things which was then
incorrectly rewritten and refixed again, but that one has a suble bug left, and
none of these really correctly fixed the stack handling, and at the end of the
day, the PDF still doesn't render.

This patchset should fix all these issues. It falls prey to the same problem of
changing xpdf code as the original patch did, but I think the stack handling is
worth it; this is really the right place to put the code, and the merge should
not be too complicated in the unlikely event that xpdf ever releases again. If
people really think it's a problem, I can personally offer to fix those merges.

Hand-crafted test-cases for the last commit may be found in my Public:
