Hello,
This is a fix for a crash in otf font rendering. Emacs crashed for me when gsub_gpos->FeatureList.FeatureCount
was zero and otf_langsys->FeatureCount was 2377.

I'm very sorry for the late response.

As this part is collecting features for a specific language,
the above change is not good. I'll fix the code so that
invalid otf_langsys->FeatureCount doesn't lead to crash.
Could you tell me which font causes this problem?
