It happens with several tests like fast/ruby/text-emphasis.html in the Debug bot. The tests seem to pass in Release and the rendering out looks correct as well removing the assert. The thing is that for some reason we can get an empty GlyphData from FontCascade::getEmphasisMarkGlyphData() when it ends up falling back to system (FontCascadeFonts::glyphDataForSystemFallback). I'm not an expert in fonts, but maybe we can just return false from FontCascade::getEmphasisMarkGlyphData() when the GlyphData obtained is empty.

Comment on attachment 263161 [details] Patch The prefix [GTK] should not be used on a patch that affects platform-independent code. Lets take that prefix off this.

Myles, can you review this?

Comment 4 2015-10-18 22:40:31 PDT

Ok, I used the GTK prefix because the assert seems to only happen in the GTK+ bots, I don't know why.

I'm not sure that "empty" is the best name.
