[tex-live] synctex problem with TeXLive 2011 on Lion

[Daniel Halperin]

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).

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.

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.

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.

Any advice? I can provide source files, logs, etc. on request. Or file a
bugreport if there's a bugzilla.

Thanks!
Dan
