Thank you for the patch. I'm now studying the code. It takes time to recall what I wrote by myself... Please wait for a while.

The calculation of the position to move to after a match and the positions for invoked lookups do not take account of ignored glyphs.

Similarly, the calculation of the position to move to for a ligature substitution is not correct, but this does not matter, for no matches will be obtained in the wrong positions.

I attach a patch, for file otfdrive.c. relative to libotf 0.9.13. It also contains an extension of the debugging information from GPOS to GSUB.
