OOM intervention triggered on loading causes DCHECK in document loader

Project Member Reported by ssid@chromium.org, May 18 2018 
Error message:

FATAL:document_loader.cc(751)] Check failed: !response_.IsNull()

I am unable to get the stack trace for some reason.

Steps to repro:
Enable OOM intervention pausing on debug build on low end device.
Load http://phukiengiabuon.vn/
The page stops loading as expected. But hits a dcheck later.

Assigning to yuzu@ for now.

I am not very familiar with the code.
Should DocumentLoader::DataReceived not be called when page is paused? What if page was paused after sending the request?

I noticed the same issue. This bug might be responsible for the higher RendererCrash rate in the intervention experiment.

It might be possible that the relevant task is getting posted to the default task queue which we can't pause. It would be very useful to see a stack trace and a location from which the task in question is posted.
