Steps to reproduce the problem:
Not sure how to reproduce at present. Need advice on what the issue might be.

What is the expected behavior?
no crashes.

What went wrong?
We have been getting intermittent crashes for weeks, so I have downloaded and built a debug chrome. 

Overnight a crash occured, the stack trace implies a gpu failure, could you give some advice on how to debug this further if it happens again?
