Got the following information from the crash report, it looks like font related issues. MozCrashReason assertion failed: self.font_contexts.lock_shared_context().has_font(&font.font_key)
There are still crash reports with this signature on Oct 24 builds. The crash reason is the same, and the only code that matches is at http://searchfox.org/mozilla-central/rev/d30462037ffea383e74c42542c820cf65b2b144e/gfx/webrender/src/glyph_rasterizer.rs#178 /cc Lee because... fonts. Also /cc nical because this assertion was added by him in WR commit 7ef93f44d3cb6.
I can reproduce this crash on Mac nightly by loading https://t.co/okjwLb98Ke from a link in Twitter. 100% reproducible.
I had to turn off webrender in nightly, because I am crashing so frequently on my 10.13 machine.
Marcia, do you have blob-images turned on? Can you still reproduce it if you turn them off?
(In reply to Jeff Muizelaar [:jrmuizel] from comment #5) > Marcia, do you have blob-images turned on? Can you still reproduce it if you > turn them off? No, that pref is set to false. I can repro using the link in Comment 3. The other data point is I am running ahead on 10.13.2 (17C60c). Lots of times when I initiate a click into a tab the whole browser goes down.
I can also reproduce this in my machine. My MacOS version is 10.13.1 and I only turned on pref "gfx.webrender.enabled".
I can 100% reproduce with my 10.13 mac. I will check this.

For the test link: http://bit.ly/2xDOl3v, it will create a big shmem data(120mb) for font data. Then, the shmem creation is failed. I think that's the reason that why wr can't find the font data for the specific font key.
With Bug 1403198, there is no raw font data in ipc. And I don't see the crash with Bug 1403198.
