I found a page in a PDF causes Poppler to get stuck in an infinate loop while rendering.<div>The same PDF renders fine in Acrobat, Apple Preview and Google Chrome - while Poppler just hangs.</div><div><div><br></div><div><meta charset="utf-8">The PDF can be downloaded from: <a href="http://midnight-labs.org/temp/hangs-poppler.pdf">http://midnight-labs.org/temp/hangs-poppler.pdf</a> (2.5mb) </div>
<div>This was extracted using pdftk (iText), the pages either side of it rendered fine.</div><div><div><br></div><div>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.</div>
<div><br></div><div>The common backtrace I've found, even after 20+ minutes of running is:</div><div><div> #12 0x0808958c in Gfx::display ()</div><div> #13 0x0808c777 in Gfx::doForm1 ()</div><div> #14 0x0808d5bd in Gfx::doTilingPatternFill ()</div>
<div> #15 0x080919bd in Gfx::doPatternFill ()</div><div> #16 0x08092128 in Gfx::opFill ()</div><div> #17 0x08089158 in Gfx::go ()</div><div> #18 0x0808958c in Gfx::display ()</div><div> #19 0x080c65b5 in Page::displaySlice ()</div>
</div></div></div><div><br></div><div>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.</div>
