it's not clear to me why a newer parser lib would fail on an older

synctex fails with lualatex on windows too. And it fails with with
the luatex version 1.06 (which is now in miktex) but not with 1.04
(texlive).
I compared the synctex files of both and the problem is that the
link to the main tex file is missing at the start.
The synctex files refers to a lot positions in input 0 but the file
list starts with
Input:1:D:/MiKTeX2.9/tex/latex/base/article.cls
I added before this line
Input:0:G:/Z-Test/./test-utf8.tex
and then synchronization worked again. Imho this is a luatex bug.
(the texlive synctex starts with number 1 and not 0
Input:1:G:/Z-Test/./test-utf8.tex)
i noticed this 0 /1 iusue too but it was ok in old viewers so mayeb that
changed .. fwiw, nothing changed in luatex where we just take the syntex
code as-is ... actually in sumatra starting at 1 is the only thing that
works
what i did notice (quick test on linux) is that the error that pops up
reports a missing source file and shows only the path part which looks
like a biug in the parser to me
there is not much documentation about the synctex file; actually, if an
editor would call out to an external program to resolve the location in
the file that would be more robust and easier to maintain, given the
one-call-per-document there is not that much gain in using a library in
the viewer; it would be easier to update and keep in sync with tex too
as now one depends on updating a viewer
