As per update in associated bug 672485 from developer this is "This is shader compiler being slow and gets killed by GPU watch dog, which is expected behavior." , However keeping this bug as open for further inputs from Internals>GPU team.

Thanks!

As mentioned above, the crash is from shader compile taking too long. Is this expected from the test case?

Also mentioned in the title  crbug.com/781443 : that bug is marked as possible duplicate of 781147, which is fixed. Is this a new case of  issue 781443 ?

 issue 781443  is a heap overflow, so this is not a duplicate. Tagging for GPU triage and +cc ccameron@ since we have a crash report.

kbr@, can you look at this? ccameron@ is unavailable.

SwiftShader doesn't appear any where in the crash stack.

Kai, could you please try to triage this? Is it reproducible?

I'll look at this when I get a chance, but I think a watchdog timeout is pretty low priority right now.

This crash is issue 672485, but since that's closed and we might have a repro case here, I'm not going to mark duplicate.
