[Poppler-bugs] [Bug 78714] Pdftoppm "Bogus memory allocation size" with high resolution raster

--- Comment #1 from Thomas Freitag <Thomas.Freitag at alfa.de> ---
Albert, I had a look into it: the pdf has one quite complex path where the
number of intersections in y direction exceeds the limit of a pointer offset
(greallocn in SplashXPathScanner::addIntersection fails and pdftoppm exits
without painting anything). What I can do here is to use
greallocn_checkoverflow instead and break the loop if memory limit is reached,
so that the pdf is rendered but the path isn't shown completely. As far as I
remember we already do that at other locations. If You agree I'll create a
patch.
