The problem seems to be the \pdfrefxform that is used by the
pdftex.def graphics driver for clipped graphics.
I have reduced the problem to the following (plain) TeX file:
-------------------------------
\output={}
\setbox0=\hbox{FORM CONTENTS}
\pdfxform 0
AAA \pdfrefxform\pdflastxform\ BBB
\vfill\eject
\end
-------------------------------
The generated synctex file (with "pdftex -synctex=-1") is
-------------------------------
SyncTeX Version:1
Input:1:mini.tex
Output:pdf

That looks invalid to me, because of the "{2 ... }1" nested inside
sheet 1.
