I found a page in a PDF causes Poppler to get stuck in an infinate loop
The same PDF renders fine in Acrobat, Apple Preview and Google Chrome -
while Poppler just hangs.
The PDF can be downloaded from:
This was extracted using pdftk (iText), the pages either side of it rendered
I've tested against todays git checkout and a ~1 month old snapshot of
Poppler on Linux, and Poppler 0.16.6 (from MacPorts) on Mac.
The common backtrace I've found, even after 20+ minutes of running is:
#12 0x0808958c in Gfx::display ()
#13 0x0808c777 in Gfx::doForm1 ()
#14 0x0808d5bd in Gfx::doTilingPatternFill ()
#15 0x080919bd in Gfx::doPatternFill ()
#16 0x08092128 in Gfx::opFill ()
#17 0x08089158 in Gfx::go ()
#18 0x0808958c in Gfx::display ()
#19 0x080c65b5 in Page::displaySlice ()
I'll file a BugZilla report later today when I've had a better look at it,
and I'm happy for the PDF to be used for regression testing etc.
