I did a reset to origin/master again Mar 21 12:57:48 2017 -0700, latest commit 21e62ae7504024888b56ae4e42d810d94812e0ae without changes.

We've never seen this on any other device. Which is why I think it is a bug in its GPU.

It has a RK3288.

The bug is hard to reproduce. We are running it in our production environment on one monitored device and handle the signal with gdb.

The reason I am compiling System WebView and Content Shell is that we had a SIGSEGV without trace, pointed to
signal 11 (SIGSEGV), code 1, fault addr 0x8 in tid 1889 (Chrome_InProcGp)
I'm not sure if this is connected but when having gdb connected CrGpuMain seams to have replaced Chrome_InProcGp.

If anyone can pinpoint a direction how this could happen, it would be of huge help for me to find a workaround.
