Crash Data

This bug was filed from the Socorro interface and is 
report bp-092ece8e-4c16-4d21-89eb-c65250170504.
=============================================================

Seen while looking at nightly crash stats - http://bit.ly/2pdsNBG. Crashes started using 20170503030212. 

Some gfx/webrender/src/renderer and rust in the signature.
I think this could be the shader compilation issues from bug 1361434.

Whiteboard: [gfx-noted]
The WR update from bug 1359744 just got merged to central, so if this is the shader compilation issue from bug 1361434 it should go away in the next nightly. (May 9 onwards)
Still around in the May 13 nightly.
Also, I filed bug 1364706 on Socorro to make this crash signature more useful, so the signature will change to:
  core::result::unwrap_failed<T> | webrender::renderer::Renderer::submit_batch
once that lands.
I think we need to add more logging in webrender and ensure that shows up in crash reports in order to actually get to the bottom of crashes like these.

There's another shader compilation issue reported in upstream WR, https://github.com/servo/webrender/issues/1251 - might or might not be the same as this. Without the logging we can't really say.
