<div>I'm running an updated version of TeXLive 2011 as indicated by the TeX Live Utility, and pdflatex (pdfTeX 3.1415926-2.3-1.40.12 (TeX Live 2011)). (OS X Lion 64-bit).</div><div><br></div><div>pdflatex seems to be producing synctex files with nested sheets, which causes synctex-parser.{c,h} to not parse tags for some \input files. This manifests by causing an unhandled exception in TeXShop (v3.05) when you try to sync on those pages. To the user, these simply appear as no-ops, but you can see the exception in the log or when debugging Xcode.</div>
<div><br></div><div>The same problem crops up even when using the standalone synctex-parser.{c,h} from CTAN, so I believe this is likely to be a problem with the pdflatex that TeXLive ships.</div><div><br></div><div>Sometimes, adding a bunch of random paragraphs to the \input file prior to the \input file whose tag isn't parsed will make synctex parse properly. I have no idea why this might happen.</div>
<div><br></div><div>Any advice? I can provide source files, logs, etc. on request. Or file a bugreport if there's a bugzilla.</div><div><br></div><div>Thanks!</div><div>Dan</div>
