Summary: Input lines spread across synctex file in MiKTeX-pdfTeX 2.9.3962 (1.40.11) 
Category: synctex
Group: None
Resolution: None

Initial Comment:
I am using MiKTeX-pdfTeX 2.9.3962 (1.40.11). On one of my larger documents, it generates a synctex file in which the "Input:" lines are spread across the file, i.e., the "Input:" lines do not form a contiguous block at the beginning of the synctex file before the "Content:" line. This breaks the synctex parser in both SumatraPDF and TeXworks.

Currently I use latexmk to fix the synctex file automatically after each build. The only thing needed is to move all the "Input:" lines to the front.

I see. I was under the impression that anything that can't be parsed by Jerome's C library is outside of the synctex version 1 specification. In particular, the _synctex_scan_preamble function seems to suggest that all "Input:" lines should appear between "SyncTeX Version:" and "Output:". That was why I decided to file the bug here. Thanks for the clarification.

This is not a pdftex problem, this is a synctex problem.
The parser breaks in that situation.
As the synctex parser code is shared by both sumatrapdf and texworks, both will fail in synchronizing.
This will be fixed in next version of the synctex library.

Attached is a minimal example that yields a synctex file with an "Input:" line after the "Content:" line. I compiled it with:

pdflatex -synctex=1 main
