This also happens on https://www.scaleway.com/pricing/ (Uploaded copy of the site, just in case it changes to http://people.igalia.com/clopez/wkbug/146194/ ) Unfortunately http://people.igalia.com/clopez/wkbug/146194/ doesn't cause an assert in a debug build on Yosemite as of r189543 :( I'm also not getting an assert on http://www.vox.com/ :( From inspection, it must be that the following is true glyphBuffer && glyphBuffer->size() == lastGlyphCount + 1 && isSoftBankEmoji(previousCharacter) but there are no m_typesettingFeatures. This is a case where the assert is wrong. Created attachment 260871 [details]
